# Question: For the data in Exercise 4 60 subtract 10 from

For the data in Exercise 4. 60, subtract 10 from each sample observation. For the new set of values, compute the mean and the deviations from the mean. How do these deviations compare to the deviations from the mean for the original sample? How does s2 for the new values compare to s2 for the old values? In general, what effect does subtracting (or adding) the same number to each observation have on s2 and s? Explain.
