The braking distances of 35 Volkswagen GTIs and 20 Ford Focuses were measured when traveling at 60 miles per hour on dry pavement. We want to test the claim that there is a difference between the mean braking distances of the two types of cars. Our hypotheses are Ho: HVW = /Ford and Ha: byw / Ford Use this information for both parts. D Question 28 1 pts Part 1: Are the requirements for the test satisfied? Why or why not? Hide O Yes, you have 55 observations in total, so the Central Limit Theorem allows you to treat the sample mean of differences as though it obeys a normal distribution. Yes, you have 55 observations in total, so the Central Limit Theorem allows you to treat both sample means (VW and Fords) as though they each follow a normal distribution. O No, the Volkswagen group has a sample size larger than 30, but you need to check that braking distances in the Fords follows a normal distribution by doing a histogram
