A small dealership leased 21 Suburu Outbacks on 2-year leases. When the cars were returned at the end of the lease, the mileage was recorded (see below). 40,010 24,996 14,340 17,359 44,712 44,525 20,239 33,348 24,299 41,782 58,313 35,886 25,765 28,937 25,069 43,302 23,958 43,526 53,617 31,803 36,704 (a) Is the dealer's mean significantly greater than the national average of 29,393 miles for 2-year leases? Using the 10 percent level of significance, choose the appropriate hypothesis. H0: μ ≤ 29,393 miles vs. H1: μ > 29,393 miles, reject H0 if tcalc > 1.3250 H0: μ ≥ 29,393 miles vs. H1: μ > 29,393 miles, reject H0 if tcalc > 1.3250 H0: μ ≤ 29,393 miles vs. H1: μ < 29,393 miles, reject H0 if tcalc > 1.3250 H1: μ ≤ 29,393 miles vs. H0: μ > 29,393 miles, reject H0 if tcalc > 1.3250 b) Calculate the test statistic.
