• Imagine that we have conducted a much larger research project using the variables in the first question (race, class and victimization)

Table 1	Race
Victimization	White	Non-white	Total
Yes	94	242	336
No	343	295	638
Total	437	537	974

• a) What is the number of degrees of freedom for Table 1?
• b) Test the null hypothesis that race and victimization are independent (alpha = .05). What do you conclude?

Imagine a separate study, using the same set of variables.

Table 2	Middle Class
Race
Victimization	White	Non-white	Total
Yes	59	160	219
No	253	224	477
Total	312	384	696

Table 3	Working Class
Race
Victimization	White	Non-white	Total
Yes	7	52	59
No	41	38	79
Total	48	90	138

• c) Which class group has the higher percentage of respondents indicating that they have been a victim of crime in the past year?
• d) For each class, test they hypothesis that race and reported victimization are independent (alpha = .01).
