Passed math Failed math Live on campus 49 21 Live off campus 28 77 ? |(a) What percentage of the students passed math? 1% |(b) What percentage of the students live on campus? % |(c) What percentage of the students who live on campus passed math? [% |(d) Is there evidence that students who live on campus tend to pass math more often than average? O No, because the percentage found in part (c) is about the same as the percentage found in part (a). O No, because the percentage found in part (c) is about the same as the percentage found in part (b). O Yes, because the percentage found in part (c) is much greater than the percentage found in part (a). O Yes, because the percentage found in part (c) is much greater than the percentage found in part (b).
