Exercise 6-22 gave data on the heights of female engineering students at ASU.
(a) Can you support a claim that mean height of female engineering students at ASU is 65 inches? Use a = 0.05
(b) What is the P-value of the test statistic computed in part (a)?
(c) Compute the power of the test if the true mean height is 62 inches.
(d) What sample size would be required to detect a true mean height of 64 inches if we wanted the power of the test to be at least 0.8?
