Question

Sketch the graph that has an area of 0.89 under the standard normal curve and to the right of the​ z-score. Then find the associated​ z-score.

Answer 1

The normal distribution is also known as the Gaussian distribution. The correct option is D, while the z-score is -2.29.

What is Normal Distribution?

The normal distribution, also known as the Gaussian distribution, is a symmetric probability distribution about the mean, indicating that data near the mean occur more frequently than data distant from the mean. The normal distribution will show as a bell curve on a graph.

Since the normal distribution is symmetrical about the mean. Therefore, 0.89 area from the left will be equal to 0.11 area from the right. Therefore, the correct option is D, while the z-score is -2.29.
