Lemon Corporation, an automobile manufacturer, is trying to determine the source of defects in some of its autos. Rumor has it that on Mondays large numbers of Lemon auto workers are hung over from a weekend of drunkenness and debauchery and are, therefore, more likely to make mistakes on the job. In order to test the hypothesis of more defects on Mondays, the company draws a random sample of 200 automobiles made by Lemon in the last two years. In this sample, they cross-tabulate the day the auto was made (Monday vs. all other days) with the variable of whether or not the care has any known defect. Based on the data below, is there support for the rumored hypothesis?
