It is believed that students who begin studying for final exams a week before the test score differently than students who wait until the night before. Suppose you want to test the hypothesis that students who study one week before score greater than students who study the night before, giving you the following hypotheses: Null Hypothesis: μ1 ≤ μ2, Alternative Hypothesis: μ1 > μ2. A random sample of 31 students who indicated they studied early shows an average score of 86.19 (SD = 4.358) and 35 randomly selected procrastinators had an average score of 84.58 (SD = 6.631). Perform a two independent samples t-test assuming that early studiers are group 1 and procrastinators are group 2. What is the test statistic and p-value of this test? Assume the population standard deviations are the same.
