In preparation for an earnings report, a large retailer wants to estimate p= the proportion of annual sales

mr Goodwill [35]

Using the z-distribution, it is found that the 95% confidence interval for the proportion of sales that occured in December is (0.1648, 0.2948).

<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.

In this problem, we have a 95% confidence level, hence $\alpha = 0.95$ , z is the value of Z that has a p-value of $\frac{1+0.95}{2} = 0.975$ , so the critical value is z = 1.96.

The sample size and the estimate are given by:

$n = 161, \pi = \frac{37}{161} = 0.2298$

Hence:

$\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.2298 - 1.96\sqrt{\frac{0.2298(0.7702)}{161}} = 0.1648$

$\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.2298 + 1.96\sqrt{\frac{0.2298(0.7702)}{161}} = 0.2948$

The 95% confidence interval for the proportion of sales that occured in December is (0.1648, 0.2948).

Simplify. Write your answer with a positive exponent.<br><br><img src="https://tex.z-dn.net/?f=%285q%5E4%29%5E3" id="TexFormula1

tresset_1 [31]

Answer:

5q^7

Step-by-step explanation:

When multiplying exponents(if positive), you must add them together. So, (5q^4)³ will be 5q^7 because the exponents were positive and they were multiplying so you add them together and leave the variable and number 5 alone.

Hope this helps! :)

Your health insurance premium is $4211 annually. If your employer pays 80% and you are paid monthly, how much is deducted from e

kakasveta [241]

<span>So if your annual monthly premium is $4211, to know how much you need to pay monthly so that would be: </span><span>$4211/12 = $350.92/month. Since your employer will be paying 80% of the amount, you will be paying the 20% of the amount monthly, so that would be .2(350.92) = $70.18/month</span>
