An investor is looking at past trends for three plans comparing dividends paid per share. She collects sample data from each plan to compare the average dividends paid per share. Let = 0.05.

Stop, the results were significant. The Tukey-Kramer post hoc test is not needed. Stop, the results were not significant. The Tukey-Kramer post hoc test is not needed. There is not enough information, so collect more data. Continue to the Tukey-Kramer post hoc test, as the results were significant. (b) The Tukey-Kramer method uses the formula (xi xj) q MSE 2 1 ni + 1 nj . Using the formula, what is the value of q from the table for this scenario? (Use a table. Round your answer to two decimal places.) (c) The Tukey-Kramer method uses the formula (xi xj) q MSE 2 1 ni + 1 nj . Using the formula, how many intervals need to be calculated for this scenario?
