The local grocery store sorted apples by size. The distribution is approximately normal. The large apples have a mean diameter of 10 cm with standard deviation equal to 0.5 cm. In a bin of 100 large apples , how many can be expected to have a diameter greater than 11.5 cm, three standard deviations above the mean? A. 10
B. 3
C. 30
D. 0
E. 50

0

Step-by-step explanation:

Approximately 0.2% of the apples will be more than three standard deviations above the mean size. In a bin of 100 apples, 0.2% of 100=0.2% apples, this rounds down to zero apples that size or larger. (In a bin of 500 apples, there could be one apple of that size.)
