An instructor of an introductory statistics course wants to compare the effectiveness of two pedagogical methods. Method A uses traditional lectures, while Method B incorporates flipped-classroom activities. Students were randomly assigned to one of the two sections at the start of the semester. Final-exam scores (out of 100) are summarized below: Method A (Traditional) Method B (Flipped) n = 24 n = 19 mean = 78.5 mean = 73.1 s = 9.2 s = 12.8 Conduct an appropriate analysis to evaluate whether the two pedagogical methods produce different mean final-exam scores. Justify your choice of procedure, report the relevant statistics, and state your conclusion in the context of the problem.

The final exam will be due by Wednesday, June 17th by 11:59pm Eastern.
