Given: n = 3159 p =86.2% = 0.862 The number of subjects used at least one prescription medication is calculated as: p=xn0.862=x3159x=2723.058x≃2723 The critical value for a 90% confidence level is 1.645, which can be obtained by using the standard normal table. The corresponding confidence interval is calculated as: D. The results tell us nothing about the proportion of college students who use at least one prescription medication.

Question

In a survey of

3159

adults aged 57 through 85 years, it was found that

86.2%

of them used at least one prescription medication. Complete parts (a) through (c) below.

a. How many of the

3159

subjects used at least one prescription medication?

27232723

(Round to the nearest integer as needed.)

b. Construct a 90% confidence interval estimate of the percentage of adults aged 57 through 85 years who use at least one prescription medication.

85.285.2%<p<87.287.2%

(Round to one decimal place as needed.)

c. What do the results tell us about the proportion of college students who use at least one prescription medication?

The results tell us that there is a 90% probability that the true proportion of college students who use at least one prescription medication is in the interval found in part (b).

The results tell us that, with 90% confidence, the probability that a college student uses at least one prescription medication is in the interval found in part (b).

The results tell us that, with 90% confidence, the true proportion of college students who use at least one prescription medication is in the interval found in part (b).

The results tell us nothing about the proportion of college students who use at least one prescription medication.

is not B which is it?
