The annual dividend rates for a random sample of 16 companies in three different industries, utilities, banking, and insurance, were recorded. The ANOVA comparing the mean annual dividend rate among three industries rejected the null hypothesis that the dividend rates were equal. The mean square error (MSE) was 3.36. The following table summarized the results:     Utilities Banking Insurance Number Sampled 5 5 6 Mean Annual Dividend Rate 11.62 15.4 17.4 When comparing the mean annual dividend rate for companies in the insurance and utilities industries, which of the following 95% confidence intervals can be constructed?   Multiple Choice   5.78 ± 2.160 × 2.40   5.78 ± 2.120 × 2.40   5.78 ± 2.160 × 1.11   5.78 ± 2.120 × 1.11
