Question 3.3. Suppose the growth of Bermuda grass from germination to lawn-care length is normally distributed with a mean of 20 days with a standard deviation of 3.3 days. The growth of buffalo grass from germination to lawn-care length is normally distributed with a mean of 21 days with a standard deviation of 2.3 days.

On which lawn would a z-score of –2.5 give a longer growing period? Explain.
