Construct a 95% confidence interval to estimate the population mean with x overbar xequals =101 and sigma equals =28 for the following sample sizes.

a) nequals = 39

b)n equals = 44

c)nequals=62

a) With 95% confidence,

when nequals = 39, the population mean is between the lower limit of

nothing and the upper limit of nothing.

(Round to two decimal places asneeded.)
