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.
