Final answer:
To find the area under the standard normal curve to the right of z=-2.3, subtract the area to the left of z=-2.3 from 1.
Step-by-step explanation:
To find the area under the standard normal curve to the right of z=-2.3, we can use the standard normal distribution table (also known as the z-table) or a calculator. The z-score for z=-2.3 can be found by subtracting the area to the left of z=-2.3 from 1. Using the z-table, we find that the area to the left of z=-2.3 is approximately 0.0107. Therefore, the area to the right of z=-2.3 is approximately 1 - 0.0107 = 0.9893.
