B) more than the critical value, we reject the null hypothesis and cannot conclude that a difference exists between the variability of customer satisfaction scores from two locations
C) less than the critical value, we can reject the null hypothesis and conclude that a difference exists between the variability of customer satisfaction scores from two locations
