Answer
$z=3$ and $z=0.25$
Work Step by Step
Using the table, the percentage of data items in a normal distribution that lie between the values can be obtained by subtracting the percentile that lies under the lower z-value from the percentile that lies under the higher z-value. Hence here if $z=3$and $z=0.25$, then between them : $99.87\%-59.87\%=40\%$
