Answers

Answer 1


1. If the obtained F value = .77 and the critical F value = 3.40, the researcher would reject the null hypothesis.
False. The obtained F value is less than the critical F value, so the researcher would fail to reject the null hypothesis.

2. The F-test is the ratio of the variance within groups over the variance between groups.
False. The F-test is the ratio of the variance between groups over the variance within groups.

3. If a researcher has found the F statistic is significant, they must then conduct an eta-squared test to be able to report which groups means are significantly different from other group means.
False. If the F statistic is significant, the researcher would conduct post-hoc tests (e.g., Tukey's HSD or Bonferroni) to determine which group means are significantly different, not an eta-squared test.

4. ANOVAs are useful for independent variables that have more than two values because this test assumes that the samples means are independent.
True. ANOVAs are designed to analyze the differences among group means in a sample, making them suitable for independent variables with more than two values.

5. In ANOVA, it is possible to have negative values for the sums of squares and the mean squares.
False. In ANOVA, sums of squares and mean squares are calculated using squared values, so they cannot be negative.

1) In hypothesis testing using ANOVA, the obtained F value is compared to the critical F value to determine whether the null hypothesis should be rejected or not. If the obtained F value is greater than the critical F value, then the researcher would reject the null hypothesis and conclude that there is a significant difference among the group means. However, if the obtained F value is less than the critical F value, then the researcher would fail to reject the null hypothesis and conclude that there is no significant difference among the group means. Therefore, in this scenario, the researcher would fail to reject the null hypothesis.

2) The F-test in ANOVA is used to compare the variance between groups to the variance within groups. The formula for the F-test is:

F = variance between groups / variance within groups

Therefore, the F-test is the ratio of the variance between groups over the variance within groups, not the other way around.

3) If the F statistic is significant, it means that there is a significant difference among the group means. However, the F test does not tell us which group means are significantly different from each other. To determine which group means are significantly different, the researcher would conduct post-hoc tests such as Tukey's HSD or Bonferroni. The eta-squared test is used to measure the effect size of the independent variable on the dependent variable, but it is not used to determine which group means are significantly different.

4) ANOVA (Analysis of Variance) is a statistical method used to test for significant differences among the means of two or more independent groups. ANOVA is a suitable test for independent variables that have more than two values because it can analyze the differences among multiple group means simultaneously.

5) In ANOVA, the total sum of squares (SST), the sum of squares between groups (SSB), and the sum of squares within groups (SSW) are calculated. The mean square between groups (MSB) and the mean square within groups (MSW) are then calculated by dividing the SSB and SSW by their respective degrees of freedom. Since all of these calculations involve squared values, the sums of squares and mean squares cannot be negative.

The area of a triangle is defined as the total region that is enclosed by the three sides of any particular triangle. Basically, it is equal to half of the base times height, i.e. A = 1/2 × b × h. As a result, in order to calculate the area of a triangular polygon, we must first determine its base (b) and height (h).

To find the area of the plate covered by the napkin:

Given :

A napkin is folded into an isosceles triangle, triangle ABC, and placed on a plate.The napkin has a perimeter of 38 centimeters.

The following steps can be used in order to determine the area of the plate covered by the napkin:

P = a + b + c   --- (1)

where a, b, and c are the length of the sides of the triangle.

Step 2 - According to the given data, the triangle is isosceles.

Therefore, the two sides are similar and the length of the base is 8 cm.

Step 3 - Now, substitute the values of the known terms in the above formula.

38 = 2L + 8

38 - 8 = 2L

L = 15 cm

Step 4 - The area of the plate covered by the napkin is given below:

The standard deviation of the sampling distribution of the sample mean is also called?

Answers

The standard deviation of the sampling distribution of the sample mean is also called standard error of the mean.

For the given question,

Standard error is a mathematical tool used in statistics to measure variability. The standard error of the mean (SEM) measures how much discrepancy is likely in a sample's mean compared with the population mean.The SEM takes the SD and divides it by the square root of the sample size. The SEM will always be smaller than the SD.

The standard error of the mean indicates how different the population mean is likely to be from a sample mean. You can decrease the standard error by increasing the sample size.

Standard error of the mean and standard deviation are both measures of variability used to summarize sets of data.  It helps you estimate how well your sample data represents the whole population by measuring the accuracy with which the sample data represents a population using standard deviation.

Hence we can conclude that the standard deviation of the sampling distribution of the sample mean is also called standard error of the mean.

Answers

Answer:

[tex]\huge\boxed{\sf A = 78.5\ ft\²}[/tex]

Step-by-step explanation:

Circumference = C = 31.4 ft

We know that,

C = 2πr

Where, r is the radius

31.4 = 2(3.14)r

31.4 = 6.28(r)

Divide 6.28 to both sides

31.4/6.28 = r

5 ft. = r

r = 5 ft.

Now,

Finding area:

A = πr²

A = (3.14)(5)²

A = (3.14)(25)

A = 78.5 ft²

[tex]\rule[225]{225}{2}[/tex]

To solve this problem, you need to find a radius... Circumference=2(3.14)(r)

2(3.14)=6.28

31.4/6.28=5=radius

A=(3.14)(r^2)

A=(3.14)(5^2)=78.5

How to Identify the Inequality of a Graph?

In an inequality graph, we the small circle at any end is shaded or full, the inequality sign used is either "less than or equal to" or "greater than or equal to" ("≤" or "≥"). If the circle is empty or not shaded, we use "less than" or "greater than" ("<" or ">").

In the graph showing Jeremy’s height above the ground at any time during the ride, we have a full circle (shaded) starting from 10, and another on the right at 50.

This implies that the range of height is from 10 to 50. Since the circle is full (shaded), then we would use "less than or equal to" and "greater than or equal to" ("≤" and "≥") in writing the inequality that represents the height.

Thus, where h is the height, the inequality would be: 10 ≤ h ≥ 50.

Answers

The probability of drawing two blue marbles if the first marble is not replaced is 1/5

How to determine the probabilities?

The probability of tossing a head and drawing a red marble

The given parameters are:

White = 1

Blue =3

Red = 2

Total = 6

The probability of a head is

P(Head)= 1/2

The probability of drawing a red marble is

P(Red)= 2/6 = 1/3

The required probability is

P = P(Head) * P(Red)

This gives

P = 1/2 * 1/3

P =1/6

The probability of drawing two blue marbles if the first marble is not replaced.

Here, we have:

P(B1) = 3/6 = 1/2

P(B2) = 2/5

The required probability is

P = P(B1) * P(B2)

The time for 168 miles is 8 hours.

Then, the time for 1 mile is 8/168 hours.

Thus, the time for 126 mile is 8/168 × 126 = 6 hours.

Hence, the time taken by Mamadou to travel 126 miles is 6 hours.

Which of the sets of ordered pairs represents a function?

A = {(−5, 5), (−2, 2), (2, −2), (5, −5)}

B = {(4, 2), (3, −2), (9, 4), (11, −3)}

Only A
Only B
Both A and B
Neither A nor B

Answers

Answer:

Both A and B

Step-by-step explanation:

A set of ordered pairs is not a function if there is a repeating output (Y value.)

Y values of A= 5, 2, -2, -5.

Y values of B= 2, -2, 4, -3.

There are no repeating outputs.

Explain why maternal effects are exhibited by bicoid and nanos, but not runt and gooseberry. Silencer sequences for runt and gooseberry repress transcription of maternal mRNA. during oocyte formation. Bicoid and Nanos proteins repress transcription of maternal mRNA, whereas Runt and Gooseberry proteins do not repress maternal transcription. RNA transcripts of bicoid and nanos are made maternal DNA during oocyte formation, whereas runt and gooseberry are transcribed after fertilization. Enhancer sequences for bicoid and nanos promote transcription of maternal mRNA during oocyte formation. Runt and Gooseberry proteins repress transcription of maternal mRNA, whereas Bicoid and Nanos proteins do not silence maternal mRNA transcription. The axis of symmetry of a parabola is x = -2.

A large part of the answer has to do with trucks and the people who drive them. Trucks come in all different sizes depending on what they need to carry. Some larger trucks are known as 18-wheelers, semis, or tractor trailers. These trucks are generally about 53 feet long and a little more than 13 feet tall. They can carry up to 80,000 pounds, which is about as much as 25 average-sized cars. They can carry all sorts of items overlong distances. Some trucks have refrigerators or freezers to keep food cold. Other trucks are smaller. Box trucks and vans, for example, hold fewer items. They are often used to carry items over shorter distances.A lot of planning goes into package delivery services. Suppose you are asked to analyze the transport of boxed packages in a new truck. Each of these new trucks measures12 feet 6 feet 8 feet. Boxes are cubed-shaped with sides of either1 foot, 2 feet, or 3 feet. You are paid $5 to transport a 1-foot box, $25 to transport a 2-foot box, and $100 to transport a 3-foot box. How many boxes fill a truck when only one type of box is used? What combination of box types will result in the highest payment for one truckload? Assume you are a system administrator in a company with 100 employees.
