Yоu hаve been аsked tо evаluate the claims оf a new diet company. Their advertising says that the typical customer loses more than 3 pounds in a month. A random sample of 10 customers is chosen and the number of pounds lost is recorded. The data is recorded below, in pounds lost. You can assume that the conditions to calculate a confidence interval and hypothesis test are met. 5.5 3.3 4.9 3.2 4.4 5.0 5.3 6.5 5.9 4.8 1) Find the mean, median and standard deviation of this data set. mean = [mean] standard deviation = [sd] median = [med] 2) You can conclude that the data set is approximately normal because [because] 3) Find the 95% confidence interval estimate for the mean number of pounds lost per month on this diet plan. [CI] 4) A hypothesis test at the 0.05 level of significance is to be done to test the claim that the mean weight loss is more than 3 pounds per month. What are the null and alternative hypotheses?
