Hold, please! ~ Ask A Nurse is a service provided to subscribers of a large health insurance company where customers can call a toll-free number and ask a nurse about non-urgent health problems. The company has set a goal that customers wait no more than 7.5 minutes on hold to speak to a nurse. In order to manage staff hours and availability, they want to set up a quality control process. They will assume that wait times are normally distributed with a standard deviation of 1.8 minutes and take a random sample of 4 calls every shift. If the mean wait time for a shift is more than 8 minutes, they will reallocate resources to try to bring the wait time down. Round all calculated values to 4 decimal places. The testable hypotheses in this situation are: Ho : µ = 7.5 vs. H. : µ > 7.5 1. Identify the consequences of making a Type l error. OA. Resources will not be reallocated when it is necessary OB. Resources will be reallocated when it is not necessary. OC. Resources will not be reallocated when it is not necessary. OD. Resources will be reallocated when it is necessary. 2. Identify the consequences of making a Type Il error. OA. Resources will be reallocated when it is not necessary. OB. Resources will be reallocated when it is necessary. OC. Resources will not be reallocated when it is not necessary. OD. Resources will not be reallocated when it is necessary 3. What is the chance management will make a Type I error with the decision rule of reallocating resources if the sample mean is more than 8 minutes? Chance of a Type I error = 4. Using the same decision rule, what is the power of the hypothesis test if the true mean time 9.5 minutes? Power =
