Prompt:

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.

Consider this scenario and respond in 350 words.
