Estimate the area percentage under a normal curve to the left of a z-score of -0.32 and 2.19

1 answer

To estimate the area percentage under a normal curve to the left of a z-score of -0.32, we can use a standard normal distribution table or a calculator to find the corresponding area. The area to the left of a z-score of -0.32 is approximately 0.3736 or 37.36%.

Similarly, to estimate the area percentage under a normal curve to the left of a z-score of 2.19, we can again use a standard normal distribution table or a calculator to find the corresponding area. The area to the left of a z-score of 2.19 is approximately 0.9857 or 98.57%.

Therefore, the estimated area percentage under a normal curve to the left of a z-score of -0.32 and 2.19 is 37.36% and 98.57%, respectively.
