# new drug that is used to treat leukemia Statistic assignment, homework help

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?

State the null hypothesis:

A.  µ=12.5

B.  µ≠12.5

C.  µ<12.5

D.  µ>12.5

Choose an item.

State the alternative hypothesis:

A.  µ=12.5

B.  µ≠12.5

C.  µ<12.5

D.  µ>12.5

Statistical Conclusion

A.  Reject the null hypothesis

B.  Do not reject the null hypothesis

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.

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.
