If the professor grades on a curve (for example, the professor could give A's to the top 10% of the class, regardless of the score), is a student better off with a grade of 87 on the exam with a mean of 71 and a standard deviation of 8 or a grade of 66 on a different exam, where the mean is 63 and the standard deviation is 3? Show your answer statistically and explain.

A student is better off with a grade of 87 on the exam with a mean of 71 and a standard deviation of 8 because the Z value for the grade of 87 is enter your response here and the Z value for the grade of 66 on the different exam is enter your response here.
