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. Âµ=12.5
B. Âµâ‰ 12.5
C. Âµ<12.5
D. Âµ>12.5
State the alternative hypothesis:
A. Âµ=12.5
B. Âµâ‰ 12.5
C. Âµ<12.5
D. Âµ>12.5

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 level of significance:
A. 0.001
B. 0.01
C. 0.05
D. 0.10

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 test statistic:
A. 0.058
B. 0.552
C. 1.058
D. 2.106
Perform calculations
Then answer the following two questions:
Critical value:
A. 0.050
B. 1.960
C. 2.086
D. 2.845
P-value:
A. p <0.001
B. 0.001 â‰¤ p <0.01
C. 0.01 â‰¤ p <0.05
D. 0.05  â‰¤ p
Statistical Conclusion
A. Reject the null hypothesis
B. Do not reject the null hypothesis
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.
2. We wish to test the claim that the mean body mass index (BMI) of men is equal to the mean BMI of women.  Use the data below to test this claim.
