How many of the CI's would you expect to contain μ b. How many of the CI's actually contain = 49? Submit Question 49?
To build a 98% CI for the mean of a population for which is 18, you take a random sample of 34 values and find that the sample mean is 212.6. Round all intermediate calculations to two decimals, then construct the CI 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. Submit Question
