Question 581254: Let the random variable X follow a normal probability distribution with a mean 10 and a standard deviation of 2.
Show your manual work of finding P(X>15).
What is known is it'll be 1 - # because the direction the sign goes, but other than that, I am not sure. Please help!

You can put this solution on YOUR website! Let the random variable X follow a normal probability distribution with a mean 10 and a standard deviation of 2.

----
z(15) = 5/2
P(x > 15) = P(z > 5/2) = normalcdf(5/2,100) = 0.0062
