HLT 362 M3 HYPOTHESIS TESTING WEEK 3
Hypothesis Testing
Problem 1
There is a new drug that is used to treat leukemia. The following data represents the remission time in weeks for a random sample of 21 patients using the drug.
10 7 32 23 22 6 16
11 20 19 6 17 35 6
10 34 32 25 13 9 6
Let X be a random variable representing the remission time in weeks for all patients using the new drug. Assume that the distribution of x is normal. A previously used drug treatment has a mean remission time of 12.5 weeks. Does the data indicate that the mean remission time using the new drug is different from 12.5 week at a level of significance of 0.01?
