(Round your answers to four decimal places.) (a) Develop a point estimate of the proportion of adults aged 18–29 who use the internet.

Answer 1

Answer: 0.9414

Explanation:

Given : One of the questions on a survey asked adults if they used the internet at least occasionally.

450 out of 478 adults aged 18–29 answered Yes.

Then, the point estimate of the proportion of adults aged 18–29 who use the internet will be :-

`p=\frac{\text{No. of adults aged 18–29 answered Yes}}{\text{total adults aged 18–29 surveyed }}\\\\=(450)/(478)=0.9414`

Thus , a point estimate of the proportion of adults aged 18–29 who use the internet= 0.9414
