I need direction to complete the calculations in Problem 1. I have found an answer, but I need to understand how to do the work. 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. 10,7,32,23,22,6,35,17,6,19,20,11,10,34,32,25,13,9,16,6,6 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?
