A STAT 2000 instructor is trying to see whether she should include a review of STAT 1000 into the course material. She selects a random sample of eleven STAT 2000 students and administers a pre-test of STAT 1000 material. She then conducts a two-lecture review session of STAT 1000 material and administers the test again and analyzes the differences in scores (in %). The instructor would like to know whether there is sufficient evidence that a review session increases students understanding by yielding higher test scores at the 10% level of significance. The sample mean of the differences in test scores was 2.05 with a standard deviation of 2.84. Assume the mean of the differences of the test scores follow a normal distribution. What is the p-value of the test? between 0.10 and 0.15 between 0.025 and 0.05 between 0.01 and 0.02 between 0.005 and 0.01 between 0.02 and 0.025
