Answer:

B. 10.

Step-by-step explanation:

This is the number of combinations of 3 from 5.

5C3 = 5! / 3! (5-3)!

= 5*4*3*2*1 / 3*2*1 * 2*1

= 5*4/2*1

= 10.

Answer:

3

Step-by-step explanation:

$y - 3 = n(x - 5)$

$3 - 3 = n(5 - 5) \\ 0 = n * 0$

$12 - 3 = n(8 - 5) \\ 9 = n * 3 \\ n = 3$

A local outdoor equipment store is being sold. The buyers are trying to estimate the percentage of items that are outdated. They

Tems11 [23]

Using the z-distribution, as we are working with a proportion, it is found that the buyers need a sample of 1505.

<h3>What is a confidence interval of proportions?</h3>

A confidence interval of proportions is given by:

$\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}$

In which:

$\pi$ is the sample proportion.

z is the critical value.

n is the sample size.

The margin of error is given by:

$M = z\sqrt{\frac{\pi(1-\pi)}{n}}$

In this problem, we have a 98% confidence level, hence $\alpha = 0.98$ , z is the value of Z that has a p-value of $\frac{1+0.98}{2} = 0.99$ , so the critical value is z = 2.327.

There is no estimate of the percentage, hence $\pi = 0.5$ , and the margin of error is of M = 0.03, hence we solve for n to find the desired sample size.
