16. A cognitive psychologist wanted to test the effects of priming a participant by either telling them that the "task they were about take was easy" or the "task they were about to take was difficult" and how this affected responses assuming that when participants with were primed with the "hard" condition, performance would decrease. Twenty participants had both conditions presented to them some with "easy" condition first and some with the "hard" condition first. The following is the mean of the difference scores for the two tasks MD=10 and a SEM=2.92 a. State the null and alternative hypotheses b. Perform a paired-samples t test with the descriptive statistics c. Is there a significant difference between the two conditions? Test using an alpha level of .05, using the direction of the test that is listed in the question. Use in answering question.
