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?
State the null hypothesis:
A. µ=12.5
B. µ≠12.5
C. µ12.5
State the alternative hypothesis:
A. µ=12.5
B. µ≠12.5
C. µ12.5
