A study of šeat bėlt ušērš and Kokusers yielded the randomly selected sample data summarized in the given table. Number of cigarettes smoked per day 1-14 15 and over Wear seat belts 185 30 50 Don't wear seat belts 155 25 55 At the 0.01 significance level, test the claim that the amount of smoking is independent of seat belt use. Which of the following is true? Select one: O a. The expected value of the test statistics is 13.50 and the critical value is 4.60, hence we conclude that the amount of smoking is dependent on seat belt use b. None of the other answers in necessary true. c. The expected value of the test statistics is 4.60 and the critical value is 9.21, hence we conclude that the amount of smoking is independent of seat belt use d. The expected value of the test statistics is 9.21 and the critical value is 5.72, hencO wo conclude that the
