A business school professor is interested to know if watching a video about the Central Limit Theorem helps students understand it. To assess this, the professor tests students’ knowledge both immediately before they watch the video and immediately after. The professor takes a sample of students, and for each one compares their test score after the video to their score before the video. Using the data below, calculate the p-value for the following hypothesis test:
H0:μafter≤μbefore
H0:μafter≤μbefore
Ha:μafter>μbefore
