A researcher affirms that the average time that students in the morning and afternoon shifts of an elementary school use social networks are the same. Therefore, independent random samples of 15 students from the morning shift and 17 from the afternoon shift are taken and the following times in minutes are observed: Morning 132 131 132 133 134 128 134 132 134 128 132 133 128 132 142 Evening 125 126 126 134 126 129 137 125 129 140 132 123 137 127 133 131 138 Assuming normality in these data, perform: a)a hypothesis test with a significance level of 0.10 for b) the hypothesis test of the researcher's statement with a significance level of 0.10, considering the result of the hypothesis test in the previous section. F
