Quizplus · Accepted Answer

To find the area under the standard normal curve between z = 1.8 and z = 2, we look up the cumulative area from the left up to each z-score in the standard normal distribution table or use a calculator. The area to the left of z = 1.8 is approximately 0.9641, and the area to the left of z = 2 is approximately 0.9772. Subtracting these gives the area between z = 1.8 and z = 2: 0.9772 - 0.9641 = 0.0131, which rounds to 0.0132.
