A vice president at a bank states which customers obtain service in an average time of 4.9 minutes of arriving at bank's drive-up service window. But a long-time customer of bank wants to test the hypothesis that average time to obtain service exceeds 4.9 minutes. The customer gathers data from 16 randomly selected customers, and computes the average time to obtain service. The sample mean time is 5.3 minutes and sample standard deviation is 1.2 minutes. Assume that the value of the test statistic is 1.46. Then the p-value of test statistic is
a. 0.9279
b. 0.0721
c. between 0.05 and 0.10
d. cannot be determined with the information provided
e. none of the above
