My 2:30 pm class had a list of words in green ink to memorize. My 4:00 pm class had a list of words in red ink to memorize. After a delay, student recalled as many words as they could. My 2:30 pm class with green ink had a mean of 27.5 words, SS = 720, n = 36. My 4:00 pm class with red ink had a mean of 23.1 words, SS = 610, n = 36.

State the null and alternative hypotheses using the appropriate symbols. (2 pts)c. Identify the critical value that will serve as the decision criterion. (1 pt)d. Compute the appropriate test statistic. Show your work and bold, underline, and italicize your final answer. (4 pts)e. State your decision regarding the null hypothesis. (1 pt)f.
