biostat exam update

well i thought i had made headway on the last problem that i wasn't able to do but the email from my professor reveals that what i had done yesterday was wrong. i just can't generate the expected values for a table of frequencies for a normal distribution. i'm not sure why, as far as i know i've tried every command that should produce the right output and multiplied each commands output by various n's to try to get to the expected values in an example table problem from the book but none of the values match.
