Question

Consider H0: µ = 40 versus H1: µ > 40.
a. A random sample of 64 observations taken from this population produced a sample mean of 43 and a standard deviation of 5. Using α = .025, would you reject the null hypothesis?
b. Another random sample of 64 observations taken from the same population produced a sample mean of 41 and a standard deviation of 7. Using α = .025, would you reject the null hypothesis?
Comment on the results of parts a and b.
