Can you please help me to find the answers to QMB statistics

Question 10 2 pts A new diet has begun to gain popularity with college age students. I want to test the diet to determine if it is, in fact, effective at helping students lose weight. I take a sample of 200 students and ask them to participate on the diet for 6-weeks. Each student is weighed at the start of the study. At the end of six weeks, the students weight is measured again. A paired analysis seems appropriate for the data collected. I entered the data into Statistix and the following printout was generated: Paired Test for Beginning - End Null Hypothesis: difference = 0 Alternative Hyp: difference * 0 Mean 1.1053 Std Error 0.4225 Lower 95% CI 0.2723 Mean - HO 1.1053 Upper 95% CI 1.9384 2.62 DF 199 D 0. 0096 Cases Included 200 Missing Cases 0 What rejection region would you use if you wanted to determine if the diet was effective at helping students lose weight, on average. Use alpha = .05. O Reject Ho if Z > 1.645 O Reject Ho if Z 1.96 or Z
