Question 12 The fundamental attribution error (FAE) in psychology is the tendency of a person to overemphasize "dispositional" factors and to underemphasize "situational" factors when attributing reasons for other people's behavior. We're interested in seeing if there's a difference in tendency to commit the FAE among groups that differ in level of psychology training. We show each participant a video on which a scenario is enacted, and we ask the participant questions about why the characters in the enactment behaved as they did. Suppose that our data are summarized in the contingency table below. Each of the 150 participants is classified according to two variables: type(s) of attributions emphasized ("Mostly situational", "Mixed", or "Mostly dispositional") and level of psychology training ("No psych training", "Psych degree, but not a psychologist", or "Psychologist"). Fill in these blanks with the frequencies expected if the two variables, level of psychology training and type(s) of attributions emphasized, are independent.
Round your answers to two or more decimal places.
