Answer:
0.0060
Step-by-step explanation:
The z-score is given by
<em>z = (866,475-722,500)/57,429 = 2.51
</em>
The probability is given by the area under the Normal curve N(0,1) to the <em>right</em> of 2.51
In <em>Excel </em> this value is found with the formula
=1-NORMDIST(2.51,0,1,1)
and in <em>OpenOffice Calc
</em>
=1-NORMDIST(2.51;0;1;1)
<em>
(NORMDIST(2.51;0;1;1) gives the area to the left of 2.51, so 1-NORMDIST(2.51;0;1;1) gives the area to the right of 2.51)
</em>
and equals 0.0060
I have worked that on paper
