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.
