Question 5

In a study of binge drinking among undergraduates at Miami, 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.
Use the numbers below for this question only!

Binge  Drinking?

YES             NO

Male            266              207

Female         244              235

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