An ornithologist is studying the length (in seconds) of bird calls. Random samplesfrom three different breeds yielded the following results.Breed 1 2.3 1.9 2.1Breed 2 0.8 1.2 1.1Breed 3 2.0 1.4 1.7Use one-way ANOVA to test if the mean call length differs for the three breeds. Use = 0.05.What are the null and alternate hypotheses?

A)

H0: 1 23; H1: 1 = 2= 3

B)

H0: 1 = 2 = 3 H1: 1 2 3

C)

H0: 1 = 2= 3; H1: Not all of 1, 2, 3 are equal.

D)

H0: 1 2 3 H1: 1 > 2 > 3

E)

none of these
