Given that z is a standard normal random variable and that the area to the right of z is 0.1949, then the value of z must be
Your high school graduating class had 564 members. Thirty-three percent of these are expected to attend college. The probability that less than 160 will attend college is
In a given year, the average annual salary of a NFL football player was $189,000 with a standard deviation of $20,500. If a sample of 50 players was taken, then probability that the sample mean will be $192,000 or more is
This solution gives the step by step method for computing probabilities based on Z score.
