Answer #1

(a) X2 = 5, df = 2

Using Table 8 in appendix A, we got P value = 0.0821

So, P value

Conclusion: Fail to reject null hypothesis because p value is insignificant.

(b) X2 = 12.1, df = 6

Using Table 8 in appendix A, we got P value = 0.0598

So, P value

Conclusion: Fail to reject null hypothesis because p value is insignificant.

(c) X2 = 21.24, df = 9

Using Table 8 in appendix A, we got P value = 0.0116

So, P value

Conclusion: Fail to reject null hypothesis because p value is insignificant.

(d) X2 = 20.92, df = 4

Using Table 8 in appendix A, we got P value = 0.0003

So, P value

Conclusion: Reject null hypothesis because p value is significant.

(e) X2 = 5.3, df = 3

Using Table 8 in appendix A, we got P value = 0.1511

So, P value

Conclusion: Fail to reject null hypothesis because p value is insignificant.
