Answer:
$13.20
Step-by-step explanation:
First, ask yourself how far way is 70 from the mean of 63.5? It is equal to 70 - 63.5 = 6.5 inches.
Next, ask yourself how many standard deviations is this? Well, every standard deviation equals 2.5 inches, so there are 6.5 / 2.5 = 2.6 standard deviations. So, 70 is exactly 2.6 standard deviations to the right of the mean.
Finally, you can use the Standard Normal to find the answer P(X>70) since this is equivalent to:
<span>P(z > 2.6) = 0.0054 or 0.54% of women will be taller than 70 inches.
