The MCAT is a standardized test used by medical schools in the admission process. The scale of the exam ranges from 3 to 45. A new type of review course for the MCAT was developed by a training company. The data file here shows MCAT score for nine students before and after taking the review course. Use Excel to conduct the test using α = 0.05 to determine if the average MCAT score is higher for students after the review course when compared with before the course. In the Excel file you submit, please write down what the null and alternative hypotheses are. Explain the test results. Hint: the null hypothesis is always based on the status quo, and the alternative hypothesis is based on the desired change.
