You may need to use the appropriate technology to answer this question. In order to determine whether or not a driver's education course improves the scores on a driving exam, a sample of 6 drivers were given the exam before and after taking the course. The results are shown below. Assume the population of differences is normally distributed. Let d= Score After - Score Before. (a) Compute the test statistic. (Round your answer to three decimal places.) (b) Using =0.05 and the p-value approach, test to see if taking the course actually increased scores on the driving exam. Calculate the p-value. (Round your answer to four decimal places.) p-value= What is your conclusion? We do not reject H0. There is no significant difference. We do not reject H0. There is a significant difference, We reject H0. There is no significant difference. We reject H0. There is a significant difference
