A. convert the arriving traffic from following a normal distribution to following an exponential
distribution.
B. convert the arriving traffic from following an exponential distribution to following a normal
distribution.
C. convert the arriving traffic from following a uniform distribution to following a Poisson
distribution.
D. convert the arriving traffic from following a Poisson distribution to following a uniform
distribution

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.
