what is the correct answer to this question?

Research indicates that people who volunteer in research studies tend to have higher intelligence than non-volunteers. To test this phenomenon, a researcher obtains a sample of 200 high school students. The students are given a description of a psychological research study and asked whether they would volunteer to participate (volunteer or not volunteer). The researcher also obtains an IQ score for each student and classifies each student into an IQ category (high, medium, and low). What kind of test should be conducted on this study? Select one: O a. One-Way Repeated-Measures ANOVA O b. Independent-samples t-test O c. Chi-Square Test for Independence O d. Factorial Between-Subjects ANOVA O e. One-sample t-test O f. One-Way Between-Subjects ANOVA O g. Dependent-samples t-test O h. Pearson's r correlation O i. Chi-Square Test for Goodness-of-Fit O j. Factorial Repeated-Measures ANOVA
