Question

Some z-score tables give the area between a score and the mean. For a z-score of -1.00 that area (in percentages) is:

Answer 1

The area between a z-score of -1.00 and the mean is approximately 84.13%.

Step-by-step explanation:

The z-score table provides the area under the normal curve to the left of a given z-score. In this case, we are looking for the area between a z-score of -1.00 and the mean.

The area to the left of a z-score of -1.00 can be found in the z-table and corresponds to approximately 15.87%. However, since we want the area between the z-score of -1.00 and the mean, we need to subtract the area to the left of -1.00 from 1.00. This gives us 1.00 - 0.1587 = 0.8413, or 84.13%.
