Question

Hypothetical data (observed frequencies, fo) are provided below on relationship between gender and fear of walking at night in their neighbor-hood (FEAR) based on GSS 2018 dat.

Afraid to Walk at Night	Men	Women	Row Total
Yes	77	175	252
No	270	259	529
Column Total	347	434	781

6. Calculate the expected frequencies (fe) – that is, the frequencies we would expect to observe if there were no relationship between sex and marital satisfaction (8 pts).

Afraid to Walk at Night	Men	Women	Row Total
Yes			252
No			529
Column Total	347	434	781

7. Calculate the number of degrees of freedom associated with the chi-square test for these data (3 pts).

8. Calculate the chi-square values (15 pts)

Cell (X,Y)	fo	fe	(fo-fe)	(fo-fe)2	[(fo-fe) 2 / fe]
Men/Yes	77
Men/No	270
Women/Yes	175
Women/No	259
Χ2=_______________

9. Suppose you obtain a chi-square statistic of 29.01. Are your results statistically significant if the critical value obtained from the distribution of chi-square is 3.841 with an alpha level of .05 using Appendix D on page 380 (5 pts)?
