Assume that a sample is used to estimate a population mean μμ. Find the 95% confidence interval for a sample of size 38 with a mean of 70.6 and a population standard deviation of 9.6. Enter your answer as an open-interval (i.e., parentheses) accurate to 3 decimal places.

95% C.I. =

The answer should be obtained without any preliminary rounding.
