heights of young adult u.s women are approximatelynormal with mean 64 inches and standard deviation 2.7 inches. What proportion of all u.s. young adult women are taller than 6 feet?
Z = (score - mean)/SD
Z = [(6*12)-64]/2.7
Find table in the back of your statistics text labeled something like "areas under normal distribution" to find the proportion related to that Z score.
Where'd the 12 come from? PLEASE HELP!
12 inches in one foot
