1. Assume there is a discrete random variable X with the following distribution: Р(X) 10% 15% X 1 25% 25% 15% 10% 3 4 6 Note that this random variable is not uniformly or normally distributed. Use Excel to graphically show that the sampling distribution of X is approximately normal distributed. (Hint: use the random number generator to draw a sample of size 2 following the given probability distribution, for 10000 times. Then calculate the average value for all the samples and plot out the distribution of the sample means.)
