solution:-
a. a point estimate of a proportion of adults aged 18 to 29 who use the internet
p = x/n = 454/478 = 0.9498
b. a point estimate of a proportion of adults aged 30 to 49 who use
the internet
p = x/n = 741/833 = 0.8896
c. a point estimate of a proportion of adults aged 50 and who use
the internet
p = x/n = 1058/1644 = 0.6436
d. younger adults are more likely to use the internet
e. the population proportion for all adults (18 years of age and
over)
=> (454+741+1058)/(478+833+1644)
=> 0.7624
