Practice calculating probabilities from the normal distribution, continuing our discussion from last time.

I encourage you to *make sketches* on a probability distribution of what you are trying to get, then plug numbers in.

The R functions you'll use most of the time for this stuff are :

 pnorm(x, mean=..., sd=...) = total probability p from -inf to x
 qnorm(p, mean=..., sd=...) = x value such that prob -inf to x is p = pnorm_inverse

google "R online" , "normal distribution calculator"

Here is a summary and exercises : openintro chap 3.1 slideshow
