a loan officer rates applicants for credit. Ratings are normally distributed. The mean is 240 and the standard deviation is 50. Find the probability that an applicant will have a rating less than 300.
-----------
z(300) = (300-240)/50 = 6/5
---
P(x < 300) = P(z < 6/5) = normalcdf(-1000,6/5) = 0.8849
====================
I used a TI-84 to get the probability.
