Question: Consider H0: = 80 versus H1: 80 for a population that is normally distributed. a. A random sample of 25 observations taken

Consider H0: µ = 80 versus H1: µ ≠ 80 for a population that is normally distributed.
a. A random sample of 25 observations taken from this population produced a sample mean of 77 and a standard deviation of 8. Using α = .01, would you reject the null hypothesis?
b. Another random sample of 25 observations taken from the same population produced a sample mean of 86 and a standard deviation of 6. Using α = .01, would you reject the null hypothesis?
