If the heights within a certain subpopulation of people are normally distributed with a mean of 180 centimeters and a standard deviation of 10 centimeters, what proportion of the people is shorter than 195 centimeters? Z=(scoremean)/SD
after finiding the proportion i looked at the "areas under the normal curve" in my book. T
The proportion to my problem was 1.5
The book gives me theanswers of .4332 or .0668....which is the correct answer and how can it be determined ?

There is only one answer and it must be greater than 0.500, since 195 exceeds the mean.
The answer (for Z = 0 to 1.5) is 0.9322. Either "the book" is wrong, or you incorrectly typed 0.9322 as 0.4322
