Do you hate Mondays? Researchers in Germany have provided another reason for you: They concluded that the risk of heart attack on a Monday for a working person may be as much as 50% greater than on any other day.1 The researchers kept track of heart attacks and coronary arrests over a period of 5 years among 330,000 people who lived near Augsberg, Germany. In an attempt to verify the researcher's claim, 200 working people who had recently had heart attacks were surveyed. The day on which their heart attacks occurred appear in the following table.

Sunday Monday Tuesday Wednesday Thursday Friday Saturday
24 36 27 26 32 26 29

Do these data present sufficient evidence to indicate that there is a difference in the percentages of heart attacks that occur on different days of the week? Test using α=.05.
