Answer the following to summarize the test of the hypothesis that the two variables leve training and type(s) of attributions emphasized are not associated. For your test, use the significance. (a) Determine the type of test statistic to use. Type of test statistic: (Choose one) (b) Find the value of the test statistic. (Round to two or more decimal places.) (c) Find the p-value. (Round to three or more decimal places.) d) Can we conclude that the variables level of psychology training and type(s) of attributions emphasized are associated? Use the 0.05 level of significance. Yes No

Transcribed Image Text:You're driving along, listening to the car radio and following the rules of the road, when, all of a sudden, a
silver sedan comes out of nowhere and darts in front of you, causing you to slam on your brakes and spill
your chicken nuggets all over the place.
"Why did that guy just cut me off?!?!?" Most of us, drivers and observers alike, would tend to attribute his
actions to "dispositional" factors: he's a terrible driver, he likes to scare people on the road, etc. We tend to
overlook the possible "situational" factors that may be contributing to his recklessness: he's rushing to the
hospital, he just spilled his own chicken nuggets and temporarily lost control of the car, etc. Psychologists
call this tendency to attribute (often incorrectly) others' actions to dispositional factors rather than to
situational factors as the fundamental attribution error.
We're interested in seeing if there's a difference in inclination to commit the fundamental attribution error
among groups that differ in level of psychology training. We choose three groups of adults to participate in
study: adults who have no psychology training, adults who have a psychology degree but who are not
practicing psychologists, and adults who are practicing psychologists. We show each participant a videotape
on which a scenario similar to the one described above was enacted. Then we ask the participants question
about why the characters in the enactment behaved as they did. We are examining the variables level of
psychology training ("no psych training", "psych degree, but not a psychologist", and "psychologist") and
type(s) of attributions emphasized ("mostly situational", "mixed", and "mostly dispositional").
Suppose that our data are those summarized in the contingency table below. Each cell of the table contai
three numbers: the first number is the observed cell frequency (fo), the second number is the expected
frequency (fp) under the assumption that the two variables level of psychology training and type(s) of
attributions emphasized are not associated, and the third number is the following value.
E
(Observed cell frequency
Expected cell frequency )"
SE
Expected cell frequency
The numbers labeled "Total" are totals for observed frequency.
