What z score has an area of 0.7123?

To find the z-score that corresponds to an area of 0.7123, you would use a standard normal distribution table or a z-score calculator.

Here are the steps:

1. Since the standard normal distribution table usually gives the probability that the score is less than your z-score, you would look for the closest probability to 0.7123 in the body of the table.

2. Once you find the closest probability, you would then look at the corresponding row and column headers to find your z-score.

However, standard normal distribution tables might not have the exact value of 0.7123. In this case, you would need to find the two closest values and then interpolate to find the most accurate z-score.

Alternatively, you can use a z-score calculator, where you would simply input the area or probability (0.7123 in this case) and it would output the corresponding z-score.

Please note that the exact z-score might vary slightly depending on the table or calculator you use due to rounding differences.
