Bank A and Bank B have each developed an improved process for serving customers. The waiting period from the moment a customer enters until he or she reaches the counter needs to be shortened. A random sample of 10 customers is selected from each bank and the results (in minutes) are shown in the accompanying data table. Complete parts (a) through (c). Click the icon to view the table. 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 = 0.05.) O A. Reject Ho. There is insufficient evidence that the means differ. O B. Do not reject Ho. There is insufficient evidence that the means differ. O C. Do not reject Ho. There is sufficient evidence that the means differ. O D. Reject Ho. There is sufficient evidence that the means differ. b. Determine the p-value in (a) and interpret its meaning. p-value = (Round to four decimal places as needed.) Interpret the p-value. Choose the correct answer below. O A. It is the probability of obtaining a sample that yields a t test statistic farther away from 0 in either direction than the computed test statistic if there is no difference in the mean waiting time between Bank A and Bank B. O B. It is the probability of obtaining a sample that yields a t test statistic farther away from 0 in the positive direction than the computed test statistic if there is no difference in the mean waiting time between Bank A and Bank B. O C. It is the probability of obtaining a sample that yields a t test statistic farther away from 0 in the negative direction than the computed test statistic if there is no difference in the mean waiting time between Bank A and Bank B. c. In addition to equal variances, what other assumption is necessary in (a)? i More Info X O A. The sample sizes must be equal. O B. The samples are specifially chosen and not independently sampled. Bank A Bank B O C. Both sampled populations are approximately normal. 2.14 3.65 O D. Both sampled populations are not approximately normal. 2.44 4.55 3.06 4.55 3.77 5.17 3.93 5.34 4.64 6.82 Click to select your answer(s). ? 4.44 6.31 4.69 7.06 5.19 8.45
