A student did not believe their teacher when they stated that students tend to make more mistakes on their homework when listening to music. The students gave 30 participants two tasks: one task was given while the participant performed simple math problems and gave a similar, but different set of math problems when not listening to music. The following is the mean of the difference scores for the two tasks M_D=4 and an SEM=1.3

1. State the null and alternative hypotheses
   b. Perform a paired samples t test with the descriptive statistics
