A hospital is trying to improve quality in every area. One of the metrics they look closely at is the quality of physicians. Several individual measurements contribute to a physician's quality score, but they have observed physician quality rankings to be normally distributed, with an average quality score of 83, and a standard deviation of 4.8. A physician score of 94 or better is considered to be exceptional.

What portion of physicians would have a quality score between 73 and 93 (inclusive) (round to the nearest 4 decimal places)?
