The contingency table shows the results of a random sample of former smokers by the number of times they tried to quit smoking before they were habit-free and gender. At = 0.05, can you conclude that the number of times they tried to quit before they were habit-free is related to gender? Perform the indicated chi-square independence test by completing parts (a) through (e). Number of times tried to quit before habit-free Gender Male Female 1 273 2-3 258 144 141 Calculate the degrees of freedom. d.f. = 2 Find the critical value. x = 5.99 (Round to two decimal places as needed.) Which region below is the correct rejection region? S OA. xx B. x > x Oc. xx OD. x = (c) Calculate the test statistic. If convenient, use technology. (Round to two decimal places as needed.) 4 or more 148 82 The contingency table shows the results of a random sample of former smokers by the number of times they tried to quit smoking before they were habit-free and gender.
