Consider the e-billing case. the mean and the standard deviation of the sample of n = 65 payment times are x⎯⎯ = 18.9317 and s = 3.9131. test h0: μ = 19.0 versus ha: μ < 19.0 by setting α equal to .01 and using a critical value rule and assume normality of the population. (round your "t" and "t0.01" answers to 3 decimal places and p-value answer to 4 decimal places. negative value should be indicated by a minus sign. use a statistical software package - e. g., minitab, megastat, etc., to derive the p-value.) t t0.01 p-value h0 at 0.01.
