Assume that a sample is used to estimate a population mean . Find the 99.5% confidence interval for a sample of size 69 with a mean of 40.9 and a standard deviation of 6.3. 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.
