GPA distribution of UPW is a normal distribution with average and standard deviation of 2.78 and .42 respectively.If you randomly chose a student’s GPA, what is the chance that the GPA is less than 3? If your know a student’s GPA is less than 3, what is the chance that his/her GPA is less than 2.5? If 10 students were chosen, what is the probability that exactly three of them have GPA between 2 and 3? If a scholarship requires a minimum GPA being top 8%, what is the minimum value of GPA to qualify such a scholarship?

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.
