Question

The SAT scores of all freshmen accepted at State University are normally distributed, with a
mean of 1,050 and a standard deviation of 120. The College of Business at State University has
accepted 620 of these freshmen into the college. All students in the college who score over 1,200
are eligible for merit scholarships. How many students can the college administration expect to
be eligible for merit scholarships?

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.
