The ANOVA test performed for 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's 95% confidence intervals are shown below. Which of these pair of cities show no significant difference between the average commute times to work?
A) Houston, Akron
B) Charlotte, Akron
C) Charlotte, Tucson
D) Houston, Tucson
