1. A new taxi driver will be making regular trips from the airport to a downtown hotel. She has heard conflicting opinions as to which of two routes takes less time. When she randomly selects which route to take for each of 10 trips, the five times (minutes) for each route are as listed in file XR14081. Using the 0.05 level, examine whether the two routes could be equally time efficient. Identify and interpret the p-value for the test.
2. Comparing the attitudes of customers at three restaurants, a researcher selects a random sample of customers from each and asks each person to rate the restaurant on a scale of 50 to 100, with 50 5 "poor" and 100 5 "excellent." Given the results in file XR14082, and using the 0.05 level of significance, examine whether the population median customer ratings for the three restaurants could be the same. Identify and interpret the p-value for the test.
The amount of money spent on lunches. The variance of nine business dinners was $6.12 and the variance of 12 business lunches was $0.87. What is the test value?
