Leases. When The Cars Were Returned At The End Of The Lease, The Mileage Was Recorded (See Below). 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). 40,002 24,936 14,315 17,360 44,725 44,535 20,211 33,319 24,292 41,700 58,333 35,898 25,792 28,916 25,070 43,397 23,912 43,506 53,630 31,826 36,719 (a) Is the dealer's mean significantly greater than the national average of 29,112 miles for 2-year leases? Using the 10 percent level of significance, choose the appropriate hypothesis. a. H0: μ ≤ 29,112 miles vs. H1: μ > 29,112 miles, reject H0 if tcalc > 1.3250 b. H0: μ ≥ 29,112 miles vs. H1: μ > 29,112 miles, reject H0 if tcalc > 1.3250 c. H0: μ ≤ 29,112 miles vs. H1: μ < 29,112 miles, reject H0 if tcalc > 1.3250 d. H1: μ ≤ 29,112 miles vs. H0: μ > 29,112 miles, reject H0 if tcalc > 1.3250 (b) Calculate the test statistic. (Round your answer to 2 decimal places.) (c) The dealer's cars show a significantly greater mean number of miles than the national average at the 10 percent level. a. No b. Yes
