To build a 95% CI for the mean of a population, you take a random sample of 13 values and find that the
sample mean is 225.3 with standard deviation 18.
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 Cl command on a calculator/computer, you might get marked wrong due to
rounding. Use the formulas given in the text/notes.
