?a) n=22
The 98?% confidence interval for the population mean when n= 22 is from a lower limit of 55.72 to an upper limit of 68.28
b) n=44
The 98?% confidence interval for the population mean when n= 44 is from a lower limit of ? to an upper limit of?
?c) n=59
The 98?% confidence interval for the population mean when n= 59 is from a lower limit of ? to an upper limit of?
