Suppose Diane and Jack are each attempting to use a simulation to describe the sampling distribution from a population that is skewed left with mean 70 and standard deviation 5. Diane obtains 1000 random samples of size n= 4 from the population, finds the mean of the means, and determines the standard deviation of the means. Jack does the same simulation, but obtains 1000 random samples of size n = 40 from the population. Complete parts (a) through (c) below....
