Question 2
A retail chain would like to test if a difference exists between the variability of customer satisfaction scores from two locations.
The following data represents satisfaction scores from a random sample of customers from these locations on a scale of 1-20.Location 1 12 14 20 18 15 17 16Location 2 18 19 17 18 16 20 Using = 0.10, the conclusion for this hypothesis test would be that because the test statistic is ___________________ _________.A) more than the critical value, we fail to reject the null hypothesis and conclude that a difference exists between the variability of customer satisfaction scores from two locations
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
D) less than the critical value, we fail to reject the null hypothesis and cannot conclude that a difference exists between the variability of customer satisfaction scores from two locations
