Question
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. Dept. 1 Dept. 2 Dept. 3 1 4096 4096 4096 4096 2048 4096 3. 4096 2048 8192 computer 4 8192 4096 8192 4096 2048 4096 6. 2048 8192 2048 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 %3D O Null hypothesis: mean for dept 1 = mean for dept 2 = mean for dept 3 Alternative: all the %3D means are different
