The following data represents the daily rental for a compact automobile charged by two car rental companies in 9 locations. You want to test whether Thrifty has a significantly different cost than Hertz, on average. Large cities were randomly sampled for the study and you may assume that car rental prices are normally distributed in the population. Conduct the appropriate test to determine if there are differences in price, on average, for cities between the two companies. Use a t-critical of 2.306. City Thrifty Hertz
Chicago 22.8 518.95
Los Angeles 29.8 948.99
Houston 17.90 19.99
Orlando 26.983 5.93
Boston 24.612 5.60
Seattle 21.962 2.99
Pittsburgh 20.901 9.99
Phoenix 47.74 36.99
New Orleans 33.81 26.90

a. What are the null and the alternative hypotheses?
b. What are the assumptions (conditions) of this test, and were they met? Why or why not?
c. Perform the appropriate test including the formula that you used, the calculated value of the t-statistic.
d. State your conclusion.
