Solution in the attachment.

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
Well 5=5
and 37/40
hmm, try to get that 40 into an nice number that is multiplule of 10
if we divide top and bottom by 4 that would work

9.25/10=92.5=100=925/1000=925 thousandths=0.925
so the decimal would be 5.925
Well im guessing it the average highway speed 60 mph so it is $7
