Using the simple random sample of weights of women from a data set, we obtain these sample statistics: n 40 and x that the population of weights of women has a standard deviation given by o = 30.26 lb. 145.87 lb. Research from other sources suggests Remember the calculator may be used for the construction of any confidence interval. Under the STAT- TEST menu you will choose either ZInterval, TInterval, or 1-PropZlnterval The best point estimate is 145.87 lb (Type an integer or a decimal.) lb u The 99% confidence interval estimate is lb (Round to two decimal places as needed.)

Charlie will perform a hypothesis test at the a = 0.05 level. Felice will perform the same test at the a = 0.01 level.
