Sex Marital Satisfaction Mal Female Row Total Satisfied 280 239 519 Unsatisfied 118 263 381 Column Total 398 502 900 6. Calculate the expected frequencies - that is, the frequencies we would expect to observe if there were no relationship between sex and marital satisfaction (8 pts). Sex Marital Satisfaction Male Female Row Total Satisfied 519 Unsatisfied 381 Column Total 398 502 900 7. Calculate the number of degrees of freedom associated with the chi-square test for these data (2 pts). 8. Calculate the chi-square values (10 pts) Cell (X.Y) O E (O-E) (0-E)2 [(O-E) 2/ EL Male/Satisfied 280 Male/unsatisfied 118 Female/satisfied 239 Female/unsatisfieed 263 Chi-square= 9. Suppose you obtain a chi-square statistic of 46.92.
