Consider the e-billing case. The mean and the standard deviation of the sample of n = 65 payment times are xx = 18.1714 and s = 3.9422. Test H₀: = 19.0 versus H_a: < 19.0 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. Negative values should be indicated by a minus sign.)
