In each of Exercises, use the Mann–Whitney test to perform the required hypothesis test Math and Chemistry. A college chemistry instructor was concerned about the detrimental effects of poor mathematics background on her students. She randomly selected 15 students and divided them according to math background. Their semester averages were the following Fewer than 2 years of high school algebra Two or more years of high school algebra 58 61 84 92 75 81 64 67 83 81 74 43 65 52 74 to conclude that, in this teacher’s chemistry courses, students with fewer than 2 years of high school algebra have a lower mean semester average than those with 2 or more years?
