(c) Suppose we want to test the null hypothesis H0: There is no association between gender and handedness vs the alternative hypothesis Ha: There is an association between gender and handedness, at the 5% level of significance. Answer the following questions.(i) What is the distribution of the test statistic for this hypothesis testii) What is the decision rule for this hypothesis test? (2 marks) We reject H0 if ?2 ? 12.5916 We reject H0 if ?2 ? 9.4877 We reject H0 if ?2 ? 5.9915 We reject H0 if ?2 ? 9.4877 We reject H0 if ?2 ? 7.3778 We reject H0 if ?2 ? 5.9915 We reject H0 if ?2 ? 12.5916 We reject H0 if ?2 ? 7.3778-What is the observed test statistic for this hypothesis test?(iv) What is the correct conclusion for this hypothesis test? (2 marks) -Since the observed test statistic is less than the critical value we reject H0 at the 5% level of significance. -Since the observed test statistic is greater than the critical value we reject H0 at the 5% level of significance. -Since the observed test statistic is less than the critical value we do not reject H0 at the 5% level of significance. -Since the observed test statistic is greater than the critical value we do not reject H0 at the 5% level of significance.
