A before and after weight in pounds was recorded fo each participant. Consider all the conditions to be met, including the population of differences is normal. Estimate the mear change in weight after 12 weeks on this program. Does the program promote weight loss? Here are the results of the study: Participant 1 2 4 Before 160.1 154.4 145.2 128.1 124.8 188.9 After 158.3 143.5 139.4 124.6 122.2 190.1 What is the mean difference? Round your final answer to 1 decimal place. Take differences as before - after. 3.9 What is the standard deviation of the differences? Round your final answer to 2 decimal places. What is the sample size? What is the critical value if researchers wish to construct a 95% confidence interval? Round your final answer to 3 decimal places. What is the lower bound of the confidence interval? Round your answer to 2 decimal places. pounds What is the upper bound of the confidence interval? Round your answer to 2 decimal places. pounds
