Answer:
0.9153
Step-by-step explanation:
Computing the z-statistics
Now we must compute the area under the Normal Curve with mean 0 and standard deviation 1 between -1.5 and 2.1
P(-1.5 < x < 2.1) = 0.9153
To compute this value we could use a calculator or a spreadsheet.
<em>In Excel or OpenOffice Calc use
</em>
<em>NORMSDIST(2.1) - NORMSDIST(-1.5)
</em>
