Problem 1

10.3 ANOVA: The Randomized Block Design

The effects of four types of graphite coater on light-box readings are to be studied. Since readings will differ from day to day, observations are taken on each of the four types every day. The results are as follows:

Graphite coater type
Day  M     A     K     L
1       4   4.8    5    4.6
2      4.8    5  5.2   4.6
3       4    4.8 5.6     5

Create the ANOVA table for this data and at the 5% level test the claim that all of the graphite coaters produce the same average light-box readings.
