The null hypothesis is Ho: OM = M2 = M3 = Hy = 45 Oui = ly = H3 = 44 OH = H2 = 43 2. This is a right tailed test with: d.f.n = and d.f.d = 3a. The STS (to 2 decimals) is F = 3b. The P-value (to 3 decimals) is: 4a. At a = 0.10, the decision is: O Accept Ha O Accept Ho O Do not reject Ho O Reject Ho 4b. The conclusion is: There is sufficient evidence to conclude that not all means are equal There is sufficient evidence to conclude that all the means are equal There is insufficient evidence to conclude that all the means are equal There is insufficient evidence to conclude that not all means are equal Submit Question

Answer 1

H₀: µ₁ = µ₂ = µ₃ = µ₄

dfn = 3

dfd = 25

F = 4.38

p-value = 0.008

Reject Ho
