Now That You Know About the Attitudes of Females and Males

Now that you know about the attitudes of females and males toward police, you want to find whether there is also a relationship between gender (female/male) and official complaints filed (yes/no) after a citizen-police encounter. You send a follow-up survey to the participants already interviewed and 198 of 220 agree to answer the question of whether they have ever filed an official complaint after a citizen-police encounter (yes/no). The results are listed in the table below. This time you select an alpha level of 0.05.
a. Identify the independent and dependent variables and indicate the level of measurement for each variable.
b. Compute the percentages for every cell.
c. State your null hypothesis and your alternative hypothesis.
d. Compute the degrees of freedom.
e. State your decision rule.
f. Compute expected frequencies for each cell.
g. Compute chi square.
h. Interpret your findings.
