You are the radiology manager. You have 8 x-ray patients arriving every hour and a mean service rate of 12 per hour. What is your capacity utilization? What is the average wait time? What is the average time in the system?

This question is worth 18 points, which is twice the other short answer questions.
For the data below give me the following:
the prediction for week 6 using a 2 point moving average
the mean absolute deviation using a 2 point moving average
the prediction for week 6 using a 3 point moving average
the mean absolute deviation using a 3 point moving average
tell me which prediction is likely more accurate and why

week 1 = 16
week 2 = 12
week 3 = 8
week 4 = 16
week 5 = 18

3. (9 points for the decision tree diagram plus 9 points for the math and making the right decision) Mammography does not prevent breast cancer but can avert a more advanced stage of cancer, thus preventing premature mortality from breast cancer. Without mammography, the incidence of breast cancer is 4.0 cases per 1000. Assume the average mammogram costs \$225 to perform. Medical treatments for advanced breast cancer are assumed to be \$150,000. Mammography can reduce the chance of advanced breast cancer to 2.4 cases per 1000.
