Question 1129926
less than 2.02
on calculator, 2nd VARS 2 and (-6, 2.02)  (you can use any other number less than -6 and get the same result.  Some use -1E99
0.9783
Greater than 1.45 (1.45, 6)
0.0735

These, one wants the z-value
z=(x-mean)/sd
>(32-40)/5 or -8/5 or -1.6 
z> -1.6 is probability (area) of 
0.9452

Fewer than 55 is z <(55-40)/5 or z<3
This has probability of 0.9987

Between 30 and 55 is a z of (30-40)/5 or -2 and a z of 3
Probability is 0.9759
