PLEASE HELP

Another issue that you have to look into is which screening test do you need to use. You have 3 conveniently named screening tests, D, E and F. Screening test Dis 80% accurate and costs $25 each. Screening Test E is 95% accurate and costs $40 each. Screening Test F is 99% accurate and costs $100 each. For anyone that tests positive on a test, they need to take a follow-up test that is definitive, and it costs $1,000 each. If the disease you are testing for occurs 2% of the time, answer the following. (Use the conditional probability calculator) Fill in the blanks: (1 pt each) Test D E F False(+) or Falsel) If the "Total Cost" to buy these tests for patients uses the formula: Total Cost = (# People taking the test)* (Cost of test) + (# People taking definitive test)*($1,000) What is the total cost of each test, assuming we buy 10,000 of them at a time. (AKA, assume 10,000 people take this test.) We are also interested in the average cost per person. So, "Total Cost" divided by 10,000 What are the total and average cost per person for this test? Fill in the blanks: (2 pts each) D E F Test Total Cost Avg Cost DE F Test Total Cost Avg Cost If test D was the standard of care and tests E and F are new, possible, standards of care, do you stick with the current standard of care or choose a new test? (Remember, you want to minimize the cost.) (1 pt) In the cancer ward, they are interested in testing a couple different therapies to extend the lives of their patients. So, they have a standard of care and are looking at 2 different "add-ons". Lets call them Add-on G and H. The test groups will be, Standard of Care, Standard of Care plus Medication G and Standard of Care plus Medication H. They were able to enroll 200 people in each group of their clinical trial. Each person was told they have about 1 year to live. So, the MTTF of the standard of care is 365 days. The standard deviation for this group is 30 days. What is the 95% confidence interval for the MTTF? (Assume MTTF +/- 2* Std Dev) (2 pts) After 1 year (365 days), from the start of treatment, there are 122 of the original 200 patients left who got the standard of care plus Add-on medication G. There are 138 patients left in the patients that got Add-on Medication H. What are your estimated MTTF for Standard Care plus Medication G or H?
