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).State the null and alternative hypotheses. Assuming independence, what are the expected frequencies for each of these variables? What is the value of the X2 statistic? The table displays data regarding the use of seat belts in relation to texting while driving. It categorizes drivers based on whether they use seat belts irregularly and whether they text while driving. - **Irregular Seat Belt Use?** - **Yes** - **Texted While Driving**: 1,737 - **Did not Text While Driving**: 1,945 - **No** - **Texted While Driving**: 2,048 - **Did not Text While Driving**: 2,775This table helps in understanding the correlation, if any, between texting while driving and the irregular use of seat belts among drivers.
