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 M_D=8 and an SEM=2.8

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?
