Assume that a sample is used to estimate a population mean μμ. Find the 99.5% confidence interval for a sample of size 59 with a mean of 62.5 and a standard deviation of 12.2. Enter your answer as an open-interval (i.e., parentheses) accurate to one decimal place (because the sample statistics are reported accurate to one decimal place). 99.5% C.I. = Answer should be obtained without any preliminary rounding. However, the critical value may be rounded to 3 decimal places.
