A school district has four schools, six class in from each school were randomly selected and the number of students in the class were recorded. Test the claim that at least one school has a different class size at a 0.01 level of significance.

School A School B School C School D
44 43 37 30
45 50 33 32
49 40 35 35
47 40 32 25
29 47 40 31
32 31 33 29

The hypotheses for this ANOVA test would be:

H0:μA=μB=μC=μDH0:μA=μB=μC=μD

HA:HA: At least one mean is different. (claim)

α=0.01α=0.01
