Certain advertisers would like to estimate the proportion of viewers
Certain advertisers would like to estimate the proportion of viewers who spend the majority of their television time watching alone. The consensus is that this percentage has been increasing over the years due to the increased number of television sets in U. S. households. a. Determine the sample size needed to construct a 90% confidence interval with a margin of error no more than 5% to estimate the true proportion of viewers who watch television alone.
b. What impact would a pilot sample that showed that 38% of viewers spend the majority of their television time watching alone have on your results?
c. Verify your results using PHStat.
