Sadie predicted that chimps who had just moved to a new enclosure would start to socialize more after the first month. She recorded how many times per day each of8 chimps shared a snack with another chimp during their first month and again during their second month in the enclosure A steps you have been taught The data are shown below Conduct an appropriate statistical test using the 7 hypothesis testing Chimp Snacks shared Snacks shared during first month 11 during second month 12 4. 6. 7. 4. 3. 01 8. 15 B. Using Sadie's data, calculate a 99% confidence interval C. sample at a different facility. He calculated both a 99% confidence interval and a 95% confidence interval, which are shown below. Identify which is which. Copy down the CIs, write "95%" next to the 95% CI, and write "99%" next to the 99% CI Henry was interested in the same prediction Sadie was, and he collected data using a different -1.95

She recorded how many times per day each of8 chimps ahared a snack with another chimp during their first month and again during their second month in the enclosure The data are shown below Conduct an appropriate statistical test using the 7 hypothesis testing steps you have bean taught. Chimp Snacks shared during first month 11 Snacks shared during second month 12 1 2. 4 8 4. 3. 15 B. Using Sadie's data, calculate z 99%% confidence interval C. Henry was interested in the same prediction Sadie was, and he collected data using a different sample at a different facility He calculated both a 99% confidence interval and a 95% confidence interval, which are shonn below. Identify which is which Copy down the CIs, write 95%6" next to the 95% CI, and nrite "99% next to the 99% CI -1.95<u<5.65 -15<u<3.85 D. Choose either one of Henry's CIs write it on your paper Then answer this question If you showed Henry this CI, and he hzd no other data from his study, should he reject his null hypothesis or not? Answer this question and explain how you can tell.
