Your professor just returned the first exam and mentioned that 60% of the class scored below the mean. Could the class scores follow a normal distribution? Explain why or why not. Where should the professor set as a C for this exam? Explain your reasoning. Note that since we are not given the mean and standard deviation of the test scores, we can't state a numerical value like 75% for a C. However, we can make more general statements about the relative location of a C.
