Shall we reject or accept the claim that there is no difference in the mean number of deer per square kilometer in these different ecological locations? Use a 10% level of significance.

a) State the null and alternate hypotheses. choose one 1. H_o: ₁ = ₂ = ₃; H₁: At least two means are equal. 2. H_o: ₁ = ₂ = ₃; H₁: Not all the means are equal. 3. H_o: ₁ = ₂ = ₃; H₁: Exactly two means are equal

b) What are the degrees of freedom? numerator and denominator

c) Interpret your conclusion in the context of the application. choose one

1. At the 10% level of significance there is sufficient evidence to conclude that the means are not all equal. 2. At the 10% level of significance there is insufficient evidence to conclude that the means are all equal. 3. At the 10% level of significance there is sufficient evidence to conclude that the means are all equal.
