Silicon chip manufacturers require the use of so-called "clean rooms" in which the air is filtered in a special way to keep the number of dust particles to a minimum.

Silicon chip manufacturers require the use of so-called "clean rooms" in which the air is filtered in a special way to keep the number of dust particles to a minimum. Five air samples were taken in each room and the dust level was measured on a scale of 1 (low) to 10 (high).
Room 1 | Room 2 | Room 3 |
5 | 3 | 1 |
6.5 | 6 | 1.5 |
4 | 4 | 3 |
7 | 4.5 | 2.5 |
6 | 3 | 4 |
a) Do an analysis of variance and interpret the result.
b) Based on the above results, if appropriate, use the Tukey-Kramer test to make all pairwise comparisons of clean rooms.
