You need the information below to answer questions 2 thru 4

The objective of a study by Crane et al. was to examine the efficacy, safety, and maternal satisfaction of (a) oral misoprostol and (b) intravenous oxytocin for labor induction in women with premature rupture of membranes at term. Researchers randomly assigned fifty two women to the oral misoprostol group and fifty three women to the intravenous oxytocin. At the end of the study, researchers measured the time in minutes to active labor. The sample distributions of the time in minutes to active labor for each of the two treatments group is given below.

a) oral misoprostol                                                                      (b) intravenous oxytocin

2) We would like to proceed with estimation by computing a 99 percent confidence interval. Which conditions for inference (if any) are we uncertain about at this point?

     a)We need to make sure the sample size is large enough. Otherwise, we would apply the Central Limit Theorem.

      b) We need to know if investigators used independent random assignment in this study.

       c) We need to check whether or not the sample distributions are severely skewed

        d) All conditions are satisfied, we can proceed with estimation.

4) The researchers believe that there will be no relationship between the two medications and the mean time to active labor. Let OM denote the oral misoprostol group and IO denote the intravenous oxytocin group.

a)What statistical hypotheses should be used to test this claim?

b)Assuming the conditions for inference are satisfied, compute the p-value and the critical value for this hypothesis test.

c)What is the interpretation of the p-value found in part b?

d)Would you expect to reject or fail to reject Ho based on your answer in Problem 3 part d? Why?

e)What does the p-value you calculated in part b suggest? .

f)State the conclusion of the test.

Explanation / Answer

answer of part(2) d.All conditions are satisfied, we can proceed with estimation.

answer of part(4) here we formulate Ho: there is no difference in OM and IO i.e. OM=IO

H1: OM is not equal to IO

here only sample size is given and other information is not given and not possible to calculate any thing.we can have following information

please supply problem 3 so that other question can be solved
