Click the icon to view the bank branch data. a. Assuming that the population variances from both banks are equal, is there evidence of a difference in the mean waiting time between the two branches? (Use a = 0.1.) Let u, be the mean waiting time of the commercial district branch and uz be the mean waiting time of the residential area branch. Determine the hypotheses. Choose the correct answer below. OB. Ho: H "2 O A. Ho: H *H2 H,: "2 OC. Ho: H 242 OD. Hai H SH2 H,: H2 Find the test statistic. STAT "O (Round to two decimal places as needed.) Find the critical value(s). (Use a comma to separate answers as needed. Round to two decimal places as needed.) Choose the correct conclusion below. O A. Do not reject H,. There is sufficient evidence that the mean waiting time between the two branches differ. B. Reject Ho. There is sufficient evidence that the mean walting time between the two branches differ. c. Do not reject Ho. There is insufficient evidence that the mean waiting time betwoen the two branches differ. D. Reject Ho. There is insufficient evidence that the mean waiting time between the two branches differ. b. Determine the p-value in (a) and interpret its meaning. p-value =O (Round to three decimal places as needed.)
