Stats Z Table Question

[cherylbishop925]

Thanks for the input. I should have time to get through instacert twice and probably most of idiots guide twice as well. Some of it is just going to remain lost on me. I have til Tuesday afternoon with not else much to do.

So far I've probably done about 3/4 of both instacert questions and idiots. I'm seem to be doing alright. The lack of a practice test is sort of disconcerting.
