If the average systolic blood pressure of normal adult males is approximately normally distributed with a mean of 121 mmHg and a standard deviation of 11.3 mmHg, find the probability that a sample of size 16 will yield a mean:
Greater than 125 mmHg


Between 117 mmHg and 127 mmHg

It is estimated that an average of 53% of college students graduate in 5 years or less. If 500 students on a large campus are selected at random, what is the probability that between 50% and 60% of them will graduate in 5 years or less?
