In order to estimate the proportion, p, of a large class
Chapter 7, Problem 5E(choose chapter or problem)
In order to estimate the proportion, \(p\), of a large class of college freshmen that had high school GPAs from \(3.2\) to \(3.6\), inclusive, a sample of \(n=50\) students was taken. It was found that \(y=9\) students fell into this interval.
(a) Give a point estimate of \(p\).
(b) Use Equation 7.3-2 to find an approximate \(95 \%\) confidence interval for \(p\).
(c) Use Equation 7.3-4 to find an approximate \(95 \%\) confidence interval for \(p\).
(d) Use Equation 7.3-5 to find an approximate \(95 \%\) confidence interval for \\(p\).
