1.Suppose your supervisor issues a survey to measure customer satisfaction at three locations in town. She suspects that there will be a difference between the three locations and that customers enjoy Location C more than Locations A and B, and is considering a change in management A and B.

She returns the data to you and asks you to compare the means in overall customer satisfaction between the three groups. What statistical test do you run to determine whether there is a significant difference between the groups? What is the logic behind this test (that is, what is going on "under the hood")? Your statistics program determines that there was a difference between the three groups and the significance level is p < .01. What does this value mean? How confident are you that a significant difference exists between groups?
