A physical ?tness test was given to a large number of college freshmen. In part of the test, each student was asked to run as far as he or she could in 10 minutes. The distance each student ran in miles was recorded and can be considered to be a random variable, say X. The data showed that the random variable X followed the log-normal distribution with μy = 0.35 and σy = 0.5, where Y = ln X. A student is considered physically ?t if he or she is able to run 1.5 miles in the time allowed. What percentage of the college freshmen would be considered physically ?t if we consider only this part of the test?
