To build a 98% Cl for the mean of a population, you take a random sample of 29 values and find that the sample mean is 218.1 with standard deviation 16.9. Round all intermediate calculations (including the critical value, Tc) to two decimals, then construct the Cl and enter like this: (min,max). Be sure to include the parentheses or you will be marked wrong. Note: if you use a built-in CI command on a calculator/computer, you might get marked wrong due to rounding. Use the formulas given in the text/notes.
