The mean SAT verbal score is 462, with a standard deviation of 98. Use the Empirical Rule to determine where: a) Approximately 68% of the students score. (Assume the data set has a bell-shaped distribution.) b) From part a, we can furthermore state that the lowest 16% of scores are below ______ and the highest 16% of scores are above ________, approximately.

Working on homework, I'm assuming the answer to part a is that "Approximately 68% of the students score between 560 and 364." I am not confident about this, though. And I am struggling to figure out how to do part b.
