Transcribed Image Text:Construct a 98% confidence interval to estimate the population mean with x = 61 and o=13 for the following sample
sizes.
a) n = 33
b) n = 48
c) n = 66
Click the icon to view the cumulative probabilities for the standard normal distribution.
a) With 98% confidence, when n = 33, the population mean is between the lower limit of and the upper limit of
(Round to two decimal places as needed.)
b) With 98% confidence, when n = 48, the population mean is between the lower limit of and the upper limit of
