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.
