the confidence interval formula for p _____ include(s) the sample proportion.

Answers

Answer 1

Yes, the confidence interval formula for p includes the sample proportion. In statistical inference, a confidence interval is a range of values that is used to estimate an unknown population parameter.

In the case of a proportion, such as the proportion of individuals in a population who have a certain characteristic, the confidence interval formula involves using the sample proportion as an estimate of the population proportion.

The formula for a confidence interval for a proportion is given by:

p ± z*sqrt((p(1-p))/n)

where p is the sample proportion, n is the sample size, and z is the z-score corresponding to the desired level of confidence. The sample proportion is used as an estimate of the population proportion, and the formula uses the sample size and the level of confidence to calculate a range of values within which the true population proportion is likely to fall.

It is important to note that the sample proportion is just an estimate, and the actual population proportion may differ from it. The confidence interval provides a range of values within which the true population proportion is likely to fall, based on the available data and the chosen level of confidence.

Step-by-step explanation:

11/12*9/22 = rational         (as the solution is 33/88 which is in p/q form with                                    q not equal to 0 and p and q as integers.)

√5 *8 = 8√5 = irrational

3 + √17 = irrational                               (sum of a rational and irrational     number is always irrational)

√3*√12 = √36 = 6= rational number

π - 2π = -π = irrational                                   (since π is irrational)

-3/8 + 3/5 = -15+24/40 = 9/40 = rational

√6/2  - 1/2 = 1/2*√6 - 1 * 1/2 = 1/2 (√6 - 1) = irrational      (in this case difference is irrational and the product is clearly irrational as well).

What does the equation 100+0.05p=0.25p represent?

Answers

The value of "p" will be "0.002".

Equation:

According to the question,

[tex]100+0.05p=0.25p[/tex]

By subtracting "0.25p" from both sides, we get

→ [tex]100+0.05p-0.25p=0.25p-0.25p[/tex]

                 [tex]100-0.2p=0[/tex]

                            [tex]100=0.2p[/tex]

Answer:

Given :-

the length of a room is 2 m longer than its breadth .if the area of its floor is 63 sq.m.calculate the length and the breadth of the room

To Find :-

Length and breadth

Answer :-

Let the length and breadth be l + 2 and l

Now,

[tex] \large \sf \: Area = l + 2 \times l [/tex]

[tex] \large \sf \: 63 = l + 2 \times \: l[/tex]

[tex] \large \sf \: 63 = 2l + {l}^{2} [/tex]

[tex] \large \sf \: {l}^{2} + 2l - 63 = 0[/tex]

[tex] \large \sf \: {l}^{2} (9l - 7l) - 63 = 0[/tex]

[tex] \large \sf \: l(l + 9) - 7(l + 9)[/tex]

Either

[tex] \large \sf \: l = - 9[/tex]

or,

On which number line do the points represent negative seven and one over two and +1? (4 points)

Answers

Answer:

A number line is used in the mathematical positioning of real numbers that include the numbers from positive infinity to negative infinity. This includes rational, irrational, fractions, and whole numbers. In this case, we are given with an expression that we have to reduce to lowest terms: negative seven and one over two and +1. The first one is equal to -7.5 while the other one is equal to +1. Positive numbers lie on the right side of zero (center of the line) while negative numbers lie on the left on the other hand. -7.5 lies between -8 and -7 while +1 lies exactly between 0 and 2. Both of which are positive numbers.

Answers

Answer: B and E

Step-by-step explanation: Trust me, this is correct

The equation of the graph representing Jenna's profit is -

y = 2.75x

What is a expression? What is a mathematical equation? What is Equation Modelling?

A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

We have Jenna's profit for selling 38 ornaments is $104.50. Suppose Jenna keeps track of the number of sales (x) and profit (y) on a graph.

Assume that the equation of the graph representing Jenna's profit is -

y = mx + c

Then, it is a basic fact that with 0 sales, $0 profit will will be there. So, the line passes through (0, 0). Hence, the y - intercept [c] = 0. Then -

slope = [m] = (104.5)/38 = 2.75

So, the equation of line would be -

y = 2.75x

Therefore, the equation of the graph representing Jenna's profit is -

y = 2.75x
