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 = - 1.2 is ______.

the percentage of scores greater than z = - 1.2 is

Explanation:

Step1: Understand the percentile concept

A percentile represents the percentage of scores that are less than or equal to a particular \(z -\)score. For \(z=-1.2\), the percentile is \(11.51\), which means \(11.51\%\) of the scores are less than or equal to \(z =- 1.2\).

Step2: Calculate the percentage of scores greater than \(z=-1.2\)

We know that the total percentage of all scores is \(100\%\). Let \(P\) be the percentage of scores greater than \(z=-1.2\). Using the formula \(P=100\%-\text{Percentile of }z =-1.2\).
Substitute the percentile value: \(P = 100 - 11.51\).

Answer:

\(88.49\%\)
