![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.

Choose the best null and alternative hypothesis statement from these choices:
Null hypothesis: all the means are different. Alternative: mean for dept 1 = mean for dept 2
= mean for dept 3
O Null: mean for dept 1 = mean for dept 2 = mean for dept 3 and Alternative: at least one
mean is different
O Null hypothesis: mean for dept 1 = mean for dept 2 Alternative: mean for dept 2 = mean for
dept 3
