Suppose you are testing H 0​ :p=0.55 versus H 1​ :p<0.55, where n=25. From your data, you calculate your test statistic value as +1.3. (a) Should you use z or t when finding a p-value for this scenario? (b) Calculate the p-value for this scenario. (c) Using a significance level of 0.071, what decision should you make (Reject H 0​ or Do Not Reject H 0​ ) ?

Answers

Answer 1

(a) We should use t-distribution since the sample size n = 25 is less than 30.

(b) The test statistic value is t = 1.3. The degrees of freedom for the t-distribution is df = n - 1 = 24. Using a t-table or calculator, the p-value for a one-tailed test with t = 1.3 and df = 24 is approximately 0.104.

(c) The significance level is 0.071. Since the p-value (0.104) is greater than the significance level (0.071), we fail to reject the null hypothesis H0: p = 0.55. We do not have enough evidence to conclude that the true proportion is less than 0.55.

b. The number of Boys and Girls.​

Answers

Answer:

a. 3g + g = 53

b. 40 boys and 13 girls

Step-by-step Explanation:

(3g = number of boys)

(g = number of girls)

3g + g =53

4g = 53

g = 13.2

53 - 13.2 = 39.8 (boys)

we round to the nearest tenth on both

girls 13.2---13

boys 39.8---40

Step-by-step explanation:

Solve for x. (Enter your answers as a comma-separated list.)

Answers

Answer:

x=1

Step-by-step explanation:

The value of x is 1 for the given determinant.

The determinant is defined as a scalar value that is associated with the square matrix. If X is a matrix, then the determinant of a matrix is represented by |X| or det (X).

Given a determinant value equal to zero,

To calculate the value of x,

Firstly, calculate the determinant as follows and equate it to zero:

[tex]1(3 \times-2-(-4\times3))-x(1 \times-2-3 \times0)+2(1\times-4-0\times3)=0\\\\[/tex]

[tex]1(-6+12)-x(-2)+2(-4)=0\\\\[/tex]

[tex]6+2x-8=0\\[/tex]

Solve like terms together and try to separate variable on LHS, so that it becomes easy to calculate the value of it.

Thus, the value of x is 1.

Triangles add to 180.

180 - 57 - 43 = 80.

Vertical angles are always equal, so they are both 80 degrees in this case.

Now we know the top triangle has 80 + 2x = 180

2x = 100

Therefore x is 50 degrees.

Answer:

let the opposite angle of 43=y

57°+43°+y=180°[by sum of all angle is 180°]

100+y=180°

y=180°-100

y=80°

opposite angle of x is equal to the 80°

so the equation will be like this

x+x+80°=180°

2x+80°=180°

2x=180°-80°

2x=100

x=100/2

x=50°

so the value of x is 50°

Solution:

Let [tex]-\dfrac{33}{16}[/tex] should be divided by x to get [tex]-\dfrac{11}{4}[/tex].

[tex]\dfrac{-\dfrac{33}{16}}{x}=-\dfrac{11}{4}[/tex]

[tex]-\dfrac{33}{16}=-\dfrac{11}{4}x[/tex]

Multiply both sides by 16.

[tex]-33=-44x[/tex]

Divide both sides by -44.

[tex]\dfrac{-33}{-44}=x[/tex]

[tex]\dfrac{3}{4}=x[/tex]

Therefore, the unknown number is [tex]\dfrac{3}{4}[/tex].

If a model of a dinosaur is 3.75 feet and the scale factor for the actual dinosaur is 1:24. What is the size, in feet, of the actual dinosaur?

Answers

Answer:     120

Step-by-step explanation:

Next, write ratios to represent the unknown actual length and width of the display to the scale length and width of the display.

LengthWidth=scaleactual=4l=scaleactual=8w

Then, write two proportions by setting the two length ratios equal to one another and the two width ratios equal to one another. The given unit is feet.

LengthWidth=4l=1160=8w=1160

Next, cross multiply each equation.

LLWW=4×160=640 feet=8×160=120 feet

Then, to find the area of the display, multiply length times width.

The actual size of the dinosaur is 90 feet.

What is a scale factor?

The ratio of the scale of an original thing to a new object that is a representation of it but of a different size is known as a scale factor (bigger or smaller).

Given:

A model of a dinosaur is 3.75 feet,

and the scale-factor for the actual dinosaur is 1:24.

So,

the size of the actual dinosaur = model size x the scale-factor

The size of the actual dinosaur = 24 x 3.75

The size of the actual dinosaur = 90 feet.

Therefore, the actual size is 90 feet.
