Which of the following percentages accurately estimates the area under a normal curve to the left of a z-score of 1.23?(1 point) Responses 10.93 percent 10.93 percent 89.07 percent 89.07 percent 0.1093 percent 0.1093 percent 0.8907 percent

Answer 1

To find the area under a normal curve to the left of a z-score of 1.23, you can use the standard normal distribution table or a calculator that provides the cumulative distribution function (CDF) for the normal distribution.

The z-score of 1.23 typically corresponds to an area (or probability) of approximately 0.8907 when you look it up in the standard normal distribution table. This means that about 89.07% of the area under the curve is to the left of a z-score of 1.23.

Therefore, the correct response is:

89.07 percent
