7- Provide an appropriate response. Which is better, a score of 92 on a test with a mean of 71 and a standard deviation of 15, or a score of 688 on a test with a mean of 493 and a standard deviation of 150? (Assume that the distributions being compared have approximately the same shape.) A score of 92 A score of 688 Both scores have the same relative position. 8- Solve the problem.
