Exercise 3 A random sample of 10 compact cars and a random sample of 10 sporty 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 Time (in seconds) Required to Accelerate from 0 to 60 mph Compact 9.3 8.1 10.2 8.8 9.0 9.3 7.7 9.2 9.4 8.6 Sporty 4.7 5.2 4.5 5.5 4.2 5.3 4.6 6.3 4.0 5.7 Estimate the difference in the mean time required to accelerate from 0 to 60 mph for sporty cars and compact cars using a 95% confidence interval. Construct the estimate under the assumption that the time required to accelerate from 0 to 60 mph for any type of car is normally distributed. Express the estimate both symbolically and verbally.
