Suppose the scores earned on a statistics test are normally distributed with a mean of 65 and a standard deviation 8. The instructor wants to curve the test scores as follows: The top 5% get an A, the next 20% get a B, the middle 50% get a C, the bottom 10% get an F, and the rest earn a D. Determine the score cutoffs for the test.
