b.) with 98% confidence when n = 41 the population mean is between the lower limit of __________ and the upper limit of _______. (Round to two decimal places as needed)
c.) with 98% confidence when n= 60 the population mean is between the lower limit of __________ and the upper limit of _____, (Round to two decimal places as needed.)
