(a) Using R, generate 10,000 observations of Y . Find the following statistics for your 10,000 obser vations: minimum, maximum, mean and variance. For each statistic, give the theoretical value that the statistic should be approximately equal to. Then produce a probability histogram of the 10,000 observations. Turn this histogram in with your assignment. Describe the histogram in words. (b) Take the 10,000 observations of Y from part (a) and calculate the following variable: u = 3 + 2 y . Find the following statistics for your 10,000 observations of this new variable: minimum, maximum, mean and variance. Then produce a probability histogram of the 10,000 observation of this new variable. Turn in this histogram with your assignment. Describe the histogram in words....
