Hypothesis Testing Answer the given problem by following the steps in hypothesis testing. Sample problem: Determine the weight of the students before and during the quarantine. Did the students lose more fat before the quarantine? Weight before quarantine: Weight during quarantine: sample mean = 4.1 kg sample mean = 5.9 kg sample standard deviation = 3.7 kg sample standard deviation = 4.1 kg sample size = n = 47 sample size = n = 42 standard error = SEM2 = 3.7/ v47 = 0.540 standard error = SEM1 = 4.1/ v42 = 0.633 measure of variability = sq root [(0.633)2 + (0.540)2] = 0.83 Step 1. Determine the null and alternative hypotheses. Но: H1:
