A sample of 801 is needed.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of , we have the following confidence interval of proportions.
In which
z is the z-score that has a p-value of .

95% confidence level
So , z is the value of Z that has a p-value of , so .
25% of U.S. homes have a direct satellite television receiver.
This means that
How large a sample is necessary to estimate the true population of homes which do with 95% confidence and within 3 percentage points?
This is n for which M = 0.03. So
Rounding up:
A sample of 801 is needed.
