For a standardized exam at your school, the mean score is 106.0 with a variance of 401.3. The school newspaper has asked you to perform a hypothesis test to find out if the variance, o", is lower among student athletes. To do so, you survey a random sample of 10 student athletes. You find the sample variance is 178.7. Under the assumption that the exam scores for student athletes follow a normal distribution, you will perform a chi-square test. Find X, the value of the test statistic for your chi-square test. Round your answer to three or more decimal places.
