Question

Urine Drug Screening was performed on 2542 applicants for career craft positions in the US Postal Service's Boston Management Sectional Center. Those testing positive for more than one drug were classified under the more serious of the drugs, so each individual only contributed to a single cell in the table. The table below shows results of drug screening by sex of application. Is there any evidence that the four screening results differ by applicants' sex? Report results in APA style. Use Chi-square Test of Association on these data.

	Negative	Marijuana	Cocaine	Other Drugs
Male	1465	146	33	28
Female	764	52	27	27
