I understand an example like:

What proportion of the distribution is between a z-score of -1 and 1?

which = .3413 + .3413 = .6826


now what id the problem is ..

what proportion of the distribution is between a z-score of 1.65 to 2.65?
 
2.65 is .9960
1.65 is .9505

Therefore .9960 - .9505 = .0455

.0455 is the proportion of the distribution between a z-score of 1.65 and 2.65

is that correct?
