Use Excel to find the sample means and standard deviations for the test scores in the stem-n-leaf plot for two different teaching methods. At = 0.05, can we support the claim that the mean test scores are lower for students taught using the traditional lab than the students taught using the interactive simulation software? Assume the population variances are approximately equal. Assume the populations are normally distributed.
