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. Useα = 0.05.What are the null and alternate hypotheses?
A)H0: μ1 ≠ μ2≠μ3; H1: μ1 = μ2= μ3
B)H0: σ1 =σ 2 =σ 3 H1: σ1 ≠σ 2 ≠σ 3
C)H0: μ1 = μ2= μ3; H1: Not all of μ1, μ2, μ3 are equal.
D)H0: μ1 ≠ μ2 ≠ μ3 H1: μ1 > μ2 > μ3
E)none of these
