For a normal distribution with a mean of 370 and a standard devidation of 47, how would I find the probability of a value being greater than or equal to 500?
So far I have
mu= 370;
sigma= 47;

Hint: What does normcdf tell you? (In fact, I think this totally gives the answer away, IF you understand what the CDF means.)
So read the help for normcdf. Then do some thinking. Your homework, not mine.
