Question

During one of the Kahana Resort’s “Trivia Nights,” 480 guests took the test on “Island Trivia.” The test average was 120 points out of a possible 200 points, with all the scores normally distributed. The standard deviation of the scores was 15 points. Prizes worth $1,000 each were given to the guests scoring over 150 points. How much prize value was given out to guests taking this “Island Trivia” test?

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.
