(2) A task to explore the CLT:
    Use the MINITAB session command:
    random 500 C1?C10 ;
      uniform 0 1 .
    Note the semicolon ending the first line, period the second. 
    This generates 10 columns of random numbers between 0 and 1, each of length 500. 
    We will take each row to be a sample of size 10, so we have 500 samples of size 10. 
    To get the means of the 10 values in each row, storing the result in a new column 
    C11, use the session command
             rmean c1?c10 c11
    Name c11 with "x?bar". Put the following results on a WORD page:
    ? descriptive stats on C1?C11
    ? histogram of C11
    Add comments on the results: do C1 to C10 have similar means and std devs? 
    Does C11 seem to follow a normal distribution? 
    Does the mean and std dev of C11 appoximately match our theory? 
    (Check the theory of the text to match this situation.)
