Curved Grading Option #1Students whose raw scores are at or above the 90th percentile will receive an A.• Students whose raw scores are in the 80th-89th percentile will receive a B.Students whose raw scores are in the 70th-79th percentile will receive a C.Students whose raw scores are in the 60th-69th percentile will receive a D.Students whose raw scores are below the 60th percentile will receive an F. 3. In order to know the cutoff exam scores required for Curved Grading Option #1, Dr. Groppe needs toknow what z-scores correspond to the upper limit percentiles. Find each z-score that correspondsto the following percentiles by using the cumulative normal distribution tables. Use the z-scorewith the percentage closest to the percentile. Round your z-scores to 2 decimal places. We'vefound the z-score of the 90th percentile for you.90th percentile 1.2880th percentile70th percentile60th percentile4. Using the z-scores found in Step 3, find the exam scores that correspond to Curved GradingOption #1. Assume that the exam scores range from 0 to 100. (Round to the nearest whole number.) Hint: Youwill need to use the z-score formula and solve for the data value.Curved Grading Option #1A:100B:C:D:F:0
