Find the critical F0-value to test the claim that the populations have the same mean. Use α = 0.05. Brand 1: n = 8, mean (x̄) = 3.0, s = 0.50 Brand 2: n = 8, x̄ = 2.6, s = 0.60 Brand 3: n = 8, x̄ = 2.6, s = 0.55

Step 1
In an ANOVA test, df1 (between groups) is k - 1, where k is the number of groups. Here, we have 3 brands, so df1 = 3 - 1 = 2. df2 (within groups) is N - k, where N is the total number of observations. Here, we have 8 observations per brand, so N = 8*3 = 24. Show more…

Find the critical value(s), t0, to test the claim that µd > 0. Assume the samples are random and dependent, and the populations are normally distributed. Use α = 0.10 and n = 15.
