Chapter , Problem 8(choose chapter or problem)
A sample of size n = 100 is taken from a population that has a proportion p = 1/5.
a. Find \(\delta\) such that \(P(|\hat{p}-p| \geq \delta)=0.025\).
b. If, in the sample, \(\hat{p}=0.25\), will the 95% confidence interval for p contain the true value of p?
