A set of data has a normal distribution with a mean of 5.1 and a standard deviation of 0.9. Find the percent of data between 4.2 and 5.1.

So:

x = (4.2-5.1)/.9 = -1

"Percent distribution" here is referring to the bell curve, so we're really talking about the area under the curve from -1 to 0.

answer: 34% :)

THANK YOU
