Without doing thecalculations, explain whether a 90% confidence interval for the population mean would be widerthan, narrowerthan, or the same as that found in part(a). Thanks

(b). A clinic offers a weight-loss 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 22 14 10 17 15 12 13 24 6 25 12 6 15 9 19 21 11 16 13 20 a. Find a 95% confidence interval for the population mean. The 95% confidence interval is from a lower limit of to an upper limit of]. (Round to two decimal places as needed.)
