The average grade for an exam is 74, and the standard deviation is 7. If 11.9% of the class is given A’s (including A-, A, and A+), and the grades follow a normal distribution, what is the lowest possible grade for an A- and what is the highest possible grade for a B+? We assume that the numerical grades the students receive are always integers. Answer using z tables.
