Management at the Mall of Elbonia wanted to determine how much time customers spend at the mall. Four surveys were administered on four different days by randomly selecting individuals as they were returning from the mall to the parking lot, and asking them to participate. One of the questions asked was how much time the customer had spent in the mall on that day.

The results of the survey are provided in the Mall Time Interview Results Excel file. Columns A through D show the time spent by the customers interviewed, according to the weekday 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 weekday and time? Explain how you determined the answer to that question.
