A dietician wants to know if the time of day influences the tendency to consume coffee. The following data represents the beverage
purchases for a random sample of cafeteria customers.
 

	Early a.m.	Late a.m.	Early p.m.	Late p.m.
Number for coffee	3	5	8	11
Number for other	52	48	51	47

The null huypothesis is that the proportions of coffee purchases throughout the day are identical. Using alpha of 0.05, what conclusion 
should the dietician reach?
