Question

In a recent poll, 787 participants were asked if they believed Doctor Assisted Suicide (DAS) should be legalized. The results of the poll are given below. Is there evidence of a relationship between gender and position on DAS? a. State the null and alternate hypotheses. b. Fin in the missing expected values below. Round your answers to one decimal place. c. The chi^2 statistic is 0.413. Find the number of degrees of freedom for this test. d. What is the critical value of the test at the 0.025 level of significance? e. Given that the statistic is 0.413, do we reject or fail to reject the null hypothesis at the 0.025 level of significance? f. State the conclusion of the hypothesis test at the 0.025 level of significance.

Explanation / Answer

a) null hypothesis: gender and position on DAS are independent

alternate hypothesis: gender and position on DAS are dependent

b)from above

hence expected freqency in cell1 =105.7 and cell 2 =28

c) degree of freedom =(rows-1)*(columns-1) =2

d) critical value=7.378

e) we fail to reject

f)we do not have sufficient evidence to conclude that gender and position on DAS are dependent
