    Consider the following two data sets.

    Data Set I 8 16 20 35
    Data Set II 5 13 17 32

    Note that each value of the second data is obtained by subtracting three from the corresponding value of the first data set.

    a. Calculate the mean for each of these two data sets. Comment on the relationship between the two means

    b. Calculate the standard deviation for each of these two data sets. Comment on the relationship between the two standard deviations.
