              This is a normal distribution with a Mean: 14 g/dL and a Standard deviation: 1 g/dL.
    A ) Hemoglobin levels less than 13:
    13 = 14 - 1 = Mean - 1 SD
    0.16  x 200 = 32
    Answer:  32 people.
    B ) Hemoglobin levels greater than 14 :
     0.50  x 200 = 100
     Answer:  100 people.
