A simple random sample of 5 recently hospitalized migraine sufferers were given a new treatment; the results are listed below. Construct the 90% confidence estimate of the mean difference in the number of migraines per month before and after the t normally distributed population. Summary of # of migraines before and after treatment (5/3, 9/9, 7/4, 5/2, 4/3) Subject A Subject B Subject C Subject D Subject E # of migraines before 5 9 15 4 # of migraines after 4 |2 "Let the first population be of the "before" results and the second population be of the "after" results." The right hand critical value is Round to 2 decimal places. The error is Round to 2 decimal places The mean difference in migraines per month is between and Round your answers to 1 decimal place.
