A simple random sample of size

nequals=1717

is drawn from a population that is normally distributed. The sample mean is found to be

x overbar equals 65x=65

and the sample standard deviation is found to be

sequals=1414.

Construct a

9595​%

confidence interval about the population mean.

The lower bound is

nothing.

The upper bound is

nothing.

​(Round to two decimal places as​ needed.)
