A Psych 144 student randomly assigns 100 participants to one of two conditions. In one condition, they complete a self-report anxiety measure on red paper. In the other condition, they complete the same measure on light blue paper. She finds that the mean anxiety score in the red-paper condition is 35 with a standard deviation of 5, while the mean anxiety score in the blue-paper condition is 30 with a standard deviation of 5. The Psych 144 student does a null hypothesis test. Based on the sample size and relationship strength, which of the following would you expect this test to show?

The difference is due to chance / not statistically significant.

The difference is real / statistically significant.

The questions on the test were identical and in the same order, but one test was printed on blue paper and the other on red paper (Teaching Psychology, May 1998). Grading only the difficult questions on the test, the researchers found that scores on the blue test had a distribution with a mean of...
