(a) Write an Excel formula to generate a random normal deviate from N(4000, 200) and copy the formula into 100 cells. (b) Find the mean and standard deviation of your sample of 100 random data values. Are you satisfied that the random data have the desired mean and standard deviation? (c) Make a histogram of your sample. Does it appear normal?
