The number 0.9967 represents the area under the standard normal curve below a particular z-score.

what is the z-score?

enter your answer, as a decimal to the nearest hundredth, in the box.

Using the normal distribution principle, the Zscore which corresponds to the area under the normal curve at P(Z < z) = 0.9967 is 2.716

To obtain the Zscore in this scenario, which is the number of standard deviations from the mean value for a given score ; we make use of Zscore calculator or a normal distribution table ;

Using a normal distribution table;

Therefore, the Zscore value is 2.716

Step-by-step explanation:

Here, we use a z-score table or calculator to look up the probability and find the corresponding z-score.

P(z < ?) = 0.9967 at z = 2.72.
