Extracted text: Assume that a sample is used to estimate the life expectancy for males in a certain county. Find the 99% confidence interval for a sample of size 51 with a mean of 45.8 years and a standard deviation of 15.3 years. 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% C.I. = Answer should be obtained without any preliminary rounding.
