In a study of the social habits of college students, a random sample of 500 students was selected from colleges around the country. To measure the level of “remote social interaction” among students, the men and women in the sample were asked to keep a log for one month, recording the time they spent either online or on the phone talking/ texting/messaging/or emailing with friends. With the data provided, the level of each student’s “remote social interaction” was categorized as light, moderate, or heavy. Results from the sample appear in the contingency table below:

Use a chi square test of independence to test a null hypothesis that the level of remote social interaction is independent of gender for the population represented in the study. Use a significance level of 5% for your test.
