Question

Consider H0: µ = 100 versus H1: µ ≠ 100.
a. A random sample of 64 observations produced a sample mean of 98. Using α = .01, would you reject the null hypothesis? The population standard deviation is known to be 12.
b. Another random sample of 64 observations taken from the same population produced a sample mean of 104. Using α = .01, would you reject the null hypothesis? The population standard deviation is known to be 12. Comment on the results of parts a and b.
