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.  µ<12.5

D.  µ>12.5

Answer:  Choose an item.

State the alternative hypothesis:

A.  µ=12.5

B.  µ≠12.5

C.  µ<12.5

D.  µ>12.5

Answer:  Choose an item.

Statistical Conclusion

A.  Reject the null hypothesis

B.  Do not reject the null hypothesis

Answer:  Choose an item.

Experimental Conclusion

A.  There is sufficient evidence to conclude that the mean remission time using the new drug is different from 12.5 week at a level of significance of 0.01.

B.  There is no sufficient evidence to conclude that the mean remission time using the new drug is different from 12.5 week at a level of significance of 0.01.

Answer:  Choose an item.
