5) A random variable Y is distributed Y~N(10,25). Find the upper quartile (third quartile). Solution? The upper quartile is a value which has 75% of the data below it. We use the inverse normal function with an area of 0.75, a mean of 10, and a standard deviation of 25, to get a value of approximately 28.9.
