An engineer wishes to determine if the stopping distance formidsize automobiles is different from that of compact automobilesat 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 ifthere is a difference in the stopping distances between Midsize andcompact cars. Copy and paste the results of the test intoyour Word document.
c) Include a carefully-worded conclusion in the both statisticalterms and in the context of the problem. (Label each part)
