Question 9 unsaved the starting salaries of individuals with an mba degree are normally distributed with a mean of $54,000 and a standard deviation of $6,000. what is the probability that a randomly selected individual with an mba degree will get a starting salary of at least $60,000
Anyway, 60,000 is one standard deviation above the mean. By the 68-95-99.7 rule 68% of the probability is between -1 and +1 standard deviations, so 34% between 0 and 1 sigma so 50%-34%=16% above one sigma.
