A researcher claims that the variation in the salaries of elementary school teachers is greater than the variation in the salaries of secondary school teachers. A sample of the salaries of 9 elementary school teachers has a variance of $9070, and a sample of the salaries of 10 secondary school teachers has a variance of $3615. At 0.05 level of significance, can the researcher conclude that the variation in the elementary school teachers’ salaries is greater than the variation in the secondary school teachers’ salaries? Required: Test Value Only the final answer should be rounded-off to TWO decimal places.
