Questions 17 - 20. A claims adjustment manager learns that her 200 employees (N = 200) spend an average of 6 hours per claims case with a standard deviation of 2 hours. The numbers of hours are normally distributed.

17. We want to answer the following question: What is the probability of finding an employee who spends more than 12 hours per claims case? So we first calculate the z score that corresponds to 12. What is that z score?

Note: This answer requires an exact answer and no partial credit will be given. The answer must be a one digit whole number (no decimals). For example: 9.

Hint: The z score formula is (Specific Score - Mean)/Standard Deviation. The specific score is 12, the mean is 6, and the standard deviation is 2.
