Question: Consider the e-billing case. The mean and the standard deviation of the sample of n = 65 payment times are xx = 18.0399 and s

Consider the e-billing case. The mean and the standard deviation of the sample of n = 65 payment times are xx = 18.0399 and s = 3.9642. Test H₀: = 18.9 versus H_a: < 18.9 by setting equal to .01 and using a critical value rule and assume normality of the population. (Round your "t" and "t_0.01"answers to 3 decimal places and p-value answer to 4 decimal places. Negative values should be indicated by a minus sign. Use a statistical software package - e.g., Minitab, MegaStat, etc., to derive the p-value.)
