It is the largest chain of casual dining restaurants in the country, with over 1,500 restaurants across the United States. The headquarters is located in Overland Park, Kansas. The company is interested in determining if mean weekly revenue differs among three restaurants in a particular city. The file entitled Applebees contains revenue data for a sample of weeks for each of the three locations. Based on the data gathered by Applebee's, can it be concluded that there is a difference in the average revenue among the three restaurants? A) The p-value = 0.004 alpha = 0.05. This indicates that we should reject the null hypothesis and conclude that there exists a difference in the average revenue among the three restaurants.
