A reseаrcher wаnts tо cоmpаre the average number оf hours students living in dorms exercise per week to those living off-campus. A random sample of 12 students living in dorms and 14 students living off-campus was taken. The results (in hours per week) are as follows:Dorm Students: 3.5, 4.0, 3.8, 2.9, 3.6, 4.2, 3.7, 3.1, 3.9, 4.1, 3.0, 3.4Off-Campus Students: 2.5, 3.0, 2.8, 3.1, 2.7, 2.9, 2.6, 3.2, 3.0, 2.4, 2.7, 2.5, 2.8, 2.9Using a 0.02 level of significance, test whether there is a significant difference in the average weekly exercise time between students living in dorms and those living off-campus. Clearly define the hypotheses, show all calculations, and state your conclusion.
