<PRE><B>Question 1012754</B>
The mean height of soldiers is 68.22 inches with a variance of 10.8. Assuming the distribution of heights to be normal, how many soldiers in a regiment of 1000 would you expect to be over 6 feet tall? 
-------
z(72 in) = (72-68.22)/10.8 = 0.35
-------
P(over 6 ft) = P(z &gt; 0.35) = 0.3632
-----
# out of 1000 = 363 when rounded down
