Suppose that the Unit 3 Test has an average of a 72 with a standard deviation of 7 points. Additionally, the test scores are known to follow a Gaussiant distribution. Which of the Empirical Rule or Chebyshevs Theorem will be used here and why? A. We will use Chebyshevs Theorem because the grades follow an asymmetric distribution. B. We will use the Empirical Fule because the grades follow an asymmetric distribution. C. We will use the Empirical Rule because the grades follow a symmetric distribution. D. We will use Chebythevs Theorem because the grades follow a symmetric distribution.
