Scenario I
You are the manager of the Gander Mountain store in Frogtown, IL.

Columns A through D show the time spent by the customers interviewed, according to the part of the week and time of day when the interviews occurred. Is there any statistically significant difference (at alpha = .05) in the average amount of time people spend in the mall based on the part of the week and time of day? To determine the answer to the question, you need appropriate answer to all of the following four questions. Remember to use your Business
