Explanation / Answer

a. Top value = Mean + 1*Standard deviation = 3427 + 600 = 4027 grams

Bottom value = Mean - 1*Standard deviation = 3427 - 600 = 2827 grams

The top value is 4027 grams

The bottom value is 2827 grams

b. Since the bottom value is 2827 < 2850 , we can say that weight of 2850 grams is not more than one standard deviation below the mean.
