Question

In the previous exercise, suppose that it is decided that a sample of 100 voters is too small to provide a sufficiently reliable estimate of the population proportion.
It is required instead that the probability that the sample proportion differs from the population proportion (whatever its value) by more than 0.03 should not exceed
0.05. How large a sample is needed to guarantee that this requirement is met?
