0 Question 18 v To build a 9196 CI for the mean of a population for which 0' is 14, you take a random sample of 31 values and find that the sample mean is 298.9. Round all intermediate calculations 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 calculatorfcomputer, you might get marked wrong due to rounding. Use the formulas given in the textr'notes. 0 Question 19 v To build a 92% CI for the mean of a population for which cr is 12, you take a random sample of 35 values and find that the sample mean is 239.9.
