Consider the e- billing case. The mean and the standard deviation of the sample of 65 payment times are 18.1077 and 3.9612, respectively.

(1) Test H0: μ < 19.5 versus Ha: μ < 19.5 by setting a equal to .01 and using a critical value rule.

(2) Interpret the (computer calculated) p-value of .0031 for the test. That is, explain how much evidence there is that H0 is false.
