Question
A clinic offers a weight-los program. The table below gives the amounts of weight loss, in pounds for a random sample of 20 of its clients at the conclusion of the program Assume that the data are normally distributed Complete parts (a) and (b) 20 16 15 10 13 B 24 # 148 10 10 15 25 15 10 8 12 25 a Find a 99% confidence interval for the population mean The 99% confidence interval is from a lower limit of to an upper limit of (Round to two decimat places as needed.) b. Without doing the calculations, explain whether a 90% confidence interval for the population mean would be wider than, narrower than, or the same as that found in part (a). Choose the correct answer below OA. It will be narrower because the reliability factor will be smaller for a 90% confidence interval than for a 99% confidence interval OB. It will be wider because the reliability factor will be smaller for a 90% confidence interval than for a 99% confidence interval. OC. It will be the same because the confidence interval is being calculated for the same data set OD. It will be wider because the reliability factor will be larger for a 90% confidence interval than for a 99% confidence interval
