Problem
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 \begin{tabular}{|c|c|} \hline z-Score & Percentile \\ \hline-1.2 & 11.51 \\ 2.3 & 98.93 \\ \hline \end{tabular} The percentage of scores greater than $z=2.3$ is
Solution
Step 1 ：The z-score of 2.3 corresponds to the 98.93 percentile. This means that 98.93% of the scores are less than or equal to a z-score of 2.3.
Step 2 ：Therefore, to find the percentage of scores greater than a z-score of 2.3, we subtract 98.93 from 100.
Step 3 ：Final Answer: The percentage of scores greater than \(z=2.3\) is \(\boxed{1.07}\).
