In the past, the mean age of students at a summer camp was 16.4 years old. A recent sample of 15 students from the camp found x = 14.5, s = 2.3. a. Build a 95% CI for the current mean age of students at the camp. Round all intermediate calculations to two decimals, then construct the Cl and enter like this: (min, max). Be sure to use parentheses or you will be marked wrong. Note: if you use a built-in Cl command on a calculator/computer, you might get marked wrong due to rounding. Use the formulas given in the text/notes. (13.34
