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 alpha equals 0.01, 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 1 2-3 4 or more Male 272 258 148 Female 147 141 78 Calculate the degrees of freedom. d.f.equals 2 Part 4 Find the critical value. chi Subscript 0 Superscript 2equals 9.21 (Round to two decimal places as needed.) Part 5 Which region below is the correct rejection region? A.chi squared less than or equals chi Subscript 0 Superscript 2 chi squaredless than or equalschi Subscript 0 Superscript 2 B.chi squared less than chi Subscript 0 Superscript 2 chi squaredless thanchi Subscript 0 Superscript 2 C.chi squared greater than or equals chi Subscript 0 Superscript 2 chi squaredgreater than or equalschi Subscript 0 Superscript 2 D.chi squared greater than chi Subscript 0 Superscript 2 chi squaredgreater thanchi Subscript 0 Superscript 2 Your answer is correct.
