Question

A sample of 1,000 adults showed that 31% of them are

smokers. To estimate the proportion of people in the entire population who smoke, what additional information would you need?

Select one:

A. The size of the population

B. The length of time the people smoked

C. All the information you need is contained in the problem

D. The amount of confidence you desire in your estimate

Answer 1

C. All the information you need is contained in the problem.

310 people of 1000 people smoke.

Explanation:

`(y)/(1000): (31)/(100)`

y · 100 = 31 · 1000

100y = 31000

100y ÷ 100 = 31000 ÷ 100

y = 310
