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 ?

- statistics -
**drwls**, Friday, February 25, 2011 at 3:24pmThere 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
