An engineer wishes to determine if the stopping distance for midsize automobiles is different from that of compact automobiles at 75 mph. The data is shown below.

Automobile 1 2 3 4 5 6 7 8 9 10

Midsize 188 190 195 192 186 194 188 187 214 203

Compact 200 211 206 297 198 204 218 212 196 193

a) State the null and alternate hypotheses.

b) Use a Wilcoxon rank sum test to determine if there is a difference in the stopping distances between Midsize and compact cars. Copy and paste the results of the test into your Word document.

c) Include a carefully-worded conclusion in the both statistical terms and in the context of the problem. (Label each part)

A research hypothesis is that the variance of stopping distances of automobiles on wet pavement is significantly greater than the variance of stopping distances of automobiles on dry pavement. In the research study, 21 automobiles traveling at the same speeds are tested for stopping distances on wet pavement and then tested for stopping distances on dry pavement. On wet pavement the standard deviation of stopping distances is 32 feet. On dry pavement, the standard deviation is 16 feet. If the...

Suppose that a population of brakes supplied has a mean stopping distance, when the brake is applied fully to a vehicle traveling at 75 mph is 268 feet. Population standard deviation is 20 feet. Suppose that you take a sample of n brakes to test and if the average stopping distance is less than or equal to a critical value, you accept the lot. If it is more than the critical value, you reject the lot. You want an alpha...
