A mark of at least 50 is required to pass a course. The marks this year run from a low of 45 to a high of 83, with a mean of 64 and a standard deviation of 5. The professor would like all students to pass, so he adjusts the marks to achieve a mean of 70 with a standard deviation of4. Is this enough to ensure that all students will pass? Work out the new marks for the lowest and highest achiever
