Question
Mr. Sanderson marks his class on a normal curve. Those with z-scores above 1.9 will recieve an A, those between 1.9 and 1.2 will receive a B, those between 1.2 and -0.6 will receive a C, those between -0.6 and -1.9 will receive a D and those under -1.9 will receive an F. Determine the percent of grades that will be A,B,C,D and F. Round two decimal places as needed in each.
Mr Sanderson marks his class on a normal curve. Those with z-scores above 1.9 will receive an A, those between 1.9 and 1.2 will receive a B, those between 1.2 and -0.6 will receive a C, those between - 0,6 and - 1.9 will
receive a D, and those under -1.9 will receive an F. Determine the percent of grades that will be A, B, C, D. and F.
