The numbers of migraine attacks for the acupuncture treatment group has a mean of 1.8 and a standard deviation of 1.4. The number of migraine attacks for the sham treatment group has a mean of 1.6 and a standard deviation of 1.2 a)Construct the 95% confidence interval estimate of the mean number of migraine attacks for those treated with acupuncture. b)Construct the 95% confidence interval estimate of the mean number of migraine attacks for those given a sham treatment. c)Compare the two confidence intervals. What would the results suggest about the effectiveness of acupuncture?
