Answer:

Step 1:  Find the score in percent for each score

<u>Erika:</u>  84%

<u>Joe:</u>  5/6 * 100 -> 83.333...%

<u>Malcolm:</u>  \sqrt{7225} -> 85%

<u>Stephanie:</u>  83/100 -> 0.83 * 100 -> 83%

Hey!

--------------------------------------------------

Find the amount of points each student earned!

Erika: 100 x 0.84 = 84 points earned out of 100.

Joe: 100 / 6 = 16.6667... x 5 = 83.333... = 83.3 points earned out of 100.

Malcolm: √7225 = 85 points earned out of 100.

Stephanie: 83/100 = 83 points earned out of 100.

--------------------------------------------------

Plot the points of each student on the number line you were given!

--------------------------------------------------

Hope This Helped! Good Luck!

In the past, 21% of all homes with a stay-at-home parent, the father is the stay-at-home parent. An independent research firm ha
Afina-wow [57]

Answer:

A sample size of 79 is needed.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of \pi, and a confidence level of 1-\alpha, we have the following confidence interval of proportions.

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

In which

z is the zscore that has a pvalue of 1 - \frac{\alpha}{2}.

For this problem, we have that:

\pi = 0.21

The margin of error is:

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

95% confidence level

So \alpha = 0.05, z is the value of Z that has a pvalue of 1 - \frac{0.05}{2} = 0.975, so Z = 1.96.  

What sample size is needed if the research firm's goal is to estimate the current proportion of homes with a stay-at-home parent in which the father is the stay-at-home parent with a margin of error of 0.09?

A sample size of n is needed.

n is found when M = 0.09. So

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

0.09 = 1.96\sqrt{\frac{0.21*0.79}{n}}

0.09\sqrt{n} = 1.96\sqrt{0.21*0.79}

\sqrt{n} = \frac{1.96\sqrt{0.21*0.79}}{0.09}

(\sqrt{n})^{2} = (\frac{1.96\sqrt{0.21*0.79}}{0.09})^{2}

n = 78.68

Rounding up to the nearest whole number.

A sample size of 79 is needed.
