In this exercise we need to make a division and evaluate the new function at 
. so we have two functions, namely:
Therefore:
So:
69 cm is one standard deviation below the mean
<span>for a normally distributed (bell curve) population </span>
<span>___ about 68% lie within one standard deviation of the mean ___ 34% above and 34% below </span>
<span>in this case , the 34% below the mean is added to the 50% above the mean (the 1/2 of the population equal to or longer than 79 cm) </span>
<span>so 84% of the population is longer than 69 cm</span>
