Find the area under the standard normal curve to the left of a. z = 0.74 b. z = −2.16 c. z = 1.02 d. z = −0.15

A. z = 0.74
  The z-score of 0.74 translates to a percentile of 0.77035. Hence, the area under the standard normal curve to the left of z-score 0.74 is ~0.77.

b. z = -2.16
   This z-score translates to a percentile of 0.015386 which is also the numerical value of the area under the curve to the left of the z-score

c. z = 1.02
   The percentile equivalent of the z-score above is 0.846. The area is also 0.846.

d. z = -0.15
   The percentile equivalent and the area is equal to 0.44. 

For the first question the answer is a, for the second c, for the third d, for the 4th b, for the 5th a
