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.
