Question 1: A school is considering two videos
for a class. Students have been randomly assigned to 2 groups, and
they all take the same written test after watching the video. The
scores are summarized below:
Video 1: sample mean = 77, sample standard deviation = 6.3,
sample size = 29
Video 2: sample mean = 78, sample standard deviation = 6.8, sample
size = 28
Conduct an analysis to determine whether there is a difference in
the test scores...
