QUESTION 2 Use minitab Suppose a sample of 20 students were given a diagnostic test before studying a particular module and then again after completing the module. We want to find out if, in general, our teaching leads to improvements in students' knowledge/skills (i.e. test scores). We can use the results from our sample of students to draw conclusions about the impact of this module in general. 92.MPJ 1) check assumption (fort show your correct 3) find the t-value...

21.HE.B: Captopril is a drug designed to lower systolic blood pressure. When subjects were treated with this drug, their systolic blood pressure readings (in mm Hg) were measured before and after the drug was taken. The results are in the accompanying table on the next page. (a) Go through “The Drill” for paired t-tests (Use a 0.05 α-level and the corresponding confidence interval.) The Drill: Assumptions and Conditions Paired Data Condition The data must be paired. Only use pairing if...
