- Marshall is superstitious and suspects that people who take the GRE while wearing the same dirty socks that they wore when they got their best score on a practice test will do better than people who do not wear these “lucky” socks. In order to test that hypothesis among college students, he made 20 students wear their “lucky” socks and 20 not wear their lucky “socks” while taking the GRE test. Although he was convinced that people who wore their “lucky” socks would score higher than people who didn’t, he wanted to be able to test the possibility that they could score lower. Their scores are as follows: “Lucky” Non-“Lucky” Sock wearers Sock Wearers 108 105 107 107 112 110 113 109 105 105 100 114 120 98 *For this problem, you will be conducting a t…) Marshall is superstitious and suspects that people who take the GRE while wearing the same dirty socks that they wore when they got their best score on a practice test will do better than people who do not wear these “lucky” socks.

If μ1 is the average number of miles that the old tires last and μ2 is the aver-age number of miles that the new tires will last, the null hypothesis to be tested is μ1 = μ2.(a) What alternative hypothesis should the departmentuse if it does not want to use the new tires unless theyare definitely proved to give better mileage? In otherwords, the burden of proof is put on the new tires, andthe old tires are to be kept unless the null hypothesis canbe rejected.(b) What alternative hypothesis should the departmentuse if it is anxious to get the new tires unless they actuallygive poorer mileage than the old tires? Note that now theburden of proof is on the old tires, which will be kept onlyif the null hypothesis can be rejected.(c) What alternative hypothesis should the departmentuse so that rejection of the null hypothesis can leadeither to keeping the old tires or to buying the newones?A soft drink filling machine, when in perfect adjustment, fills the bottles with 12 ounces of soft drink.
