Question

use the information shown below to fill in the blank so that the resulting statement is true.
the percentage of scores greater than ( z = 2.3 ) is

the percentage of scores greater than ( z = 2.3 ) is

Explanation:

Step1: Understand the percentile concept

The percentile of a z - score represents the percentage of scores that are less than or equal to that z - score.

Step2: Calculate the percentage of scores greater than \(z = 2.3\)

If the percentile of \(z = 2.3\) is \(98.93\), it means that \(98.93\%\) of the scores are less than or equal to \(z = 2.3\).
To find the percentage of scores greater than \(z = 2.3\), we use the formula \(100\%-\text{Percentile of }z\).
So, \(100 - 98.93=1.07\)

Answer:

\(1.07\%\)
