Statistics

One of the questions in the Pew Internet & American Life Project asked adults if they used the Internet, at least occasionally. The results showed that 454 out of 478 adults aged 18 - 29 answered yes; 741 out of 833 adults aged 30 – 49 answered yes; 1058 out of 1644 adults aged 50 and over answered yes.

a.) Develop a point estimate of the proportion of adults aged 18 – 29 who use the Internet.
My answer: 0.9497

e.) Suppose your target population of interest is that of all adults (18 years of age and over). Develop an estimate of the proportion of that population who use the Internet.

I need clarification on e) I'm not exactly sure how to go about solving for a population. Thank you for the help.
