Exhibit 13.3 The ANOVA test performed for Exhibit 13.2 determined that not all mean commute times across the four cities are equal.However,it did not indicate which means differed.To find out which population means differ requires further analysis of the direction and the statistical significance of the difference between paired population means.Fisher 95% confidence intervals are shown below. Refer to Exhibit 13.3.Which of the following is the value used to calculate the Fisher 95% confidence intervals?
A)1.725
B)2.086
C)2.080
D)2.090
