Suppose the average annual in state tuition and required fees for a public 4-year institutions follows a Normal distribution with a population mean of $9,529 and population standard deviation of $1765.

What is the probability that a randomly selected public 4- year institution cost more than $17,000 in a year?
What proportion of public 4- year institution cost between $7500 to $12500 per year?
What is the interquartile range of public 4- year institution cost?
What cost would place a public 4-year institution into the lowest 10%?.

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
