Elementary Statistics Unit 4 : Section 1 Exercises Exercise 6 A random sample of 10 compact cars, 10 mid-size cars, and 10 luxury cars were selected. The time (in seconds) each of the randomly selected cars required to accelerate from 0 to 60 mph was looked up on the Autos.com website. The results are presented below. Car Type Compact 9.3 . Mid-Size Luxury . .3 Conduct a hypothesis test using or = 0.05 to determine whether the mean time required to accelerate from 0 to 60 mph is the same for compact, mid-size, and luxury cars. Elementary Statistics Unit 4 : Section 1 Exercises Exercise 7 Use the sample data collected in Exercise 6 to construct all pairwise comparison confidence intervals to estimate the difference in the mean time required to accelerate from 0 to 60 mph for compact, mid-size, and luxury cars with a simultaneous confidence level of 95%.
