I was thinking it would be c. must be more than 30 samples selected from each population because of the t-statistic test or would it mean less than 30 samples?

test the null hypothesis that μ1=μ3, where μi represents the true mean for treatment i, against the alternative that at least two of the means differ. Use a=0.01. choose the correct conclusion below

a. reject Ho. There is sufficient evidence to indicate difference among the means.

b. Do not reject Ho. There is insufficient evidence to indicate differences among the means.

c. Reject Ho. There is insufficient evidence to indicate difference among the means.

Do not reject Ho. There is sufficient evidence to indicate difference among the means.

Determine the conclusion for the hypothesis test. Choose the correct answer below

a. reject the null hypothesis, there is sufficient evidence to conclude that at least two of the states differ with respect to the mean discount percentages.

b. Fail to reject the null hypothesis. There is insufficient evidence to conclude that at least two of the state differ with respect ti the mean substance discount percentages.

c. Reject the null hypothesis. There is insufficient evidence to conclude that at least two of the states are equal with respect to the mean substance discount percentages.

d. Fail to reject the null hypothesis. There is sufficient evidence to conclude that at least two of the states are equal with respect to the mean substance discount percentages.
