Answer:

0.9153

Step-by-step explanation:

Computing the z-statistics

$\bf a=\frac{1.0085-1.0100}{0.0030/\sqrt{9}}=-1.5\\b=\frac{1.0121-1.0100}{0.0030/\sqrt{9}}=2.1$

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>
