The area under the normal distribution curve between z = -0.90 and z = 3.05 is found by calculating the cumulative probability for each z-value and subtracting them. The cumulative probability for z = -0.90 is approximately 0.1841 and for z = 3.05 is approximately 0.9981. Subtracting these gives 0.9981 - 0.1841 = 0.814, which is closest to 0.815.
