Essay

The marketing management of a shopping complex food court, wants to investigate the average age of customers of three of the food court's fast food outlets: fish and chips, sandwich bar, and chicken and chips. This is to ascertain whether they should be providing different seating options for patrons.
They take a random sample of eight customers at each of these three outlets and record their ages.
Do these data provide enough evidence at the 5% significance level to infer that there are differences in ages among the customers of the fast food outlets, and that the food court should provide different seating options? From previous analyses, ages of customers of this food court are normally distributed.
