Answer:

Amy will need to read 1 page each day.

Step-by-step explanation:

Total number of page of the magazine = 137 pages

Read pages of the magazine = 42 pages

Remaining pages to be read = 137 pages - 42 pages  = 95 pages

She spends 10 days reading the same number of pages each day until she finishes.

The number of pages read in each of the 10 days = 95 pages / 10 days

                                                           = 9.5 pages

In 10 days Amy reads 9.5 pages

In a day she reads ?

10 days -----------> 9.5 pages

1 day ----------------> ?

= 0.95 page

approximately 1 page per day

Thus, Amy will need to read 1 page each day.

<h2>Answer with explanation:</h2>

As per given , we have

\hat{p}=0.48   , n=331

Critical value for 90% Confidence interval : z_{\alpha/2}=1.645

a) Confidence interval :

\hat{p}\pm z_{\alpha/2}\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}

0.48\pm (1.645)\sqrt{\dfrac{0.48(1-0.48)}{331}}\\\\\approx 0.48\pm0.02746\\\\=(0.48-0.02746,\ 0.48+0.02746)\\\\=(0.45254,\ 0.50746)

Hence, a 90% confidence interval for the proportion of Americans who decide to not go to college because they cannot a ord it : (0.45254,\ 0.50746)

b) Margin of error : E=1.5%=0.015

Formula for sample size : n=p(1-p)(\dfrac{z_{\alpha/2}}{E})^2

For p =0.48 , we  have

n=0.48(1-0.48)(\dfrac{1.645}{0.015})^2=3001.88373333\approx3002

Hence, the required sample size to survey = 3002
