Question 1162486
z=(x-mean)/sd
so the first z is (148.1-162.2)/46.8 and the second is (204-162.2)/46.8, which are z s of -0.30 and 0.89 which is probability of 0.4312 or 43.12%

The calculator is nice for this 2nd VARS 2normalcdf ENTER (148.1,204,162.2,46.8) ENTER and probability of 0.4325 or 43.25%, the difference being rounding in the first.  Many are excluded with these specifications.
