# Question Suppose that the pages per book in a library are normally distributed with an unknown mean and standard deviation. The book lengths of 39 randomly sampled books are used to estimate the mean of the population. What t-score should be used to find the 99% confidence interval for the population mean? Use the portion of the table from the book or a calculator. If you use a calculator, round your answer to three decimal places.
