Placebo Chantix 805 Number in group 129 Number experiencing Insomnia 19 13 at the 0.05 level of significance, test the claim that the number experiencing insomnia is the same in a. both groups. Does there appear to be a difference? Use the critical value method. Find the 95% confidence interval for the difference in the proportion of those experiencing insomnia in the Chantix group and those experiencing insomnia in the placebo group. What can you conclude from this interval? C . Are the hypothesis test and the confidence interval giving the same result? 2 A simple random sample of front-seat occupants involved in car crashes is obtained.

C Construct the 90% confidence interval estimate of the difference between the fatality rates for interval? those not wearing seatbelts and those wearing seat belts. What can you conclude from this b. At the 0.10 level of significance, test the claim that the fatality rate is higher for occupants not wearing seat belts. Does it appear that seat belts improve safety? Use the p-value method. 3. Among 2739 female atom bomb survivors from Hiroshima and Nagasaki, 1397 developed thyroid disease.
