Question:

In a study of high school students at least 16 years of age, researchers obtained the survey results summarized in the table below (based on data from "Texting While Driving and Other Risk Motor Vehicle Behaviors Among U.S. High School Students" by O'Malley, Shults, and Eaton, Pediatrics, Vol. 131, No.6).

Irregular Seat Belt Use?
Yes No
Texted While Driving 1737 2048
Did not Text While Driving 1945 2775

Question 1: State the null and alternative hypotheses.

Question 2: Assuming independence, what are the expected frequencies for each of these variables?

Question 3: What is the value of the X2 statistic?

Question 4: Use a 0.05 significance level to test the claim of independence between texting while driving and irregular seat belt use. Are those two risky behaviors independent of each other? Calculate the chi-square manually or using Excel.
