The contingency table shows the results of a random sample of fatally injured passenger vehicle drivers (with blood alcohol concentrations greater than or equal to 0.08) by age and gender. At alpha equals 0.10, can you conclude that age is related to gender in such alcohol-related accidents? Perform the chi-square independence test by completing parts (a) through (e) below. Gender 16-20 21-30 31-40 41-50 51-60 61 and older Male 43 153 85 73 52 33 Female 10 34 21 20 10 10 d.f.equals 5 (Type a whole number.) Part 4 Find the critical value. chi Subscript 0 Superscript 2equals 9.24 (Round to two decimal places as needed.) Part 5 Which region below is the correct rejection region? A.chi squared greater than or equals chi Subscript 0 Superscript 2 chi squaredgreater than or equalschi Subscript 0 Superscript 2 B.chi squared less than chi Subscript 0 Superscript 2 chi squaredless thanchi Subscript 0 Superscript 2 Your answer is not correct.C.chi squared greater than chi Subscript 0 Superscript 2 chi squaredgreater thanchi Subscript 0 Superscript 2 This is the correct answer.D.chi squared less than or equals chi Subscript 0 Superscript 2 chi squaredless than or equalschi Subscript 0 Superscript 2 Part 6 (c) Calculate the test statistic. chi squaredequals enter your response here (Round to two decimal places as needed.)
