In a study of binge drinking among undergraduates at Ohio University, a researcher was interested in gender differences as related to binge drinking and to drinking-related arrests. She wanted to know two things: (a) Is there a significant relationship between gender and binge drinking (as defined by 5 or more drinks at one sitting), and (b) Is there a significant relationship between gender and drinking-related arrests? A random sample of males and females were asked about their experiences with binge drinking and with drinking-related arrests.

A.Use the numbers below for this question only!

Binge Drinking?

YES NO

Male 243 280

Female 214 264

What would the expected value for the "male-yes" cell be?

A study conducted at a major university indicates that the tendency among undergraduates to seek the assistance of helper differs by ethnic group. You select 25 subjects each from two different ethnic groups or business majors and count the number who sought help. In ethic group A, 11 sought out helpers at some point. In ethnic group B, 17. What are the frequency expected values for each group? Do results support the earlier study? What does the alternate hypothesis suggest...
