Texting and Seat Belt Use In a study of high school students at least 16 years of age, researchers obtained survey results summarized in the accompanying table (based on data from

“Texting While Driving and Other Risky Motor Vehicle Behaviors Among U. S. High School Students,” by O’Malley, Shults, and Eaton, Pediatrics, Vol. 131, No. 6). 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?
