We continue our analysis from previous problem set, this time examining the relationship between social class (CLASS) and spending on welfare (NATFARE).

	Social Class
Spending on Welfare	Lower Class	Working Class	Middle Class	Upper Class	Total
Too little	22	95	80	8	205
About right	14	111	131	8	264
Too much	11	126	97	9	243
Total	47	332	308	25	712

• What is the number of degrees of freedom for this table?

• Calculate the chi-square.
