We asked UST employees to tell us how many megabytes of memory (RAM) they
have on their computer. We would like to test to see if the mean amount of memory
is the same for three different academic departments. We have the memory
amounts for six faculty members' machines in the three departments shown below.

After ANOVA, assume that we want to do the pairwise comparison test of the mean
Pro
for department 1 to the mean for department 2.
The only thing I need you to do is calculate the t test statistic.
