    P()----> Area less than z value
    R()----> Area greater than z value
    Q()----> Area between 0 and z value

    If anyone is wondering how to do something like P(-2.8 < Z < 1.4) = 0.9167
    the step for that is shift stat/dist, distribution, p, then do P(1.4)
    then do the same for P(-2.8)
    The final answer is whatever value you get for P(1.4) subtracted by P(-2.8) which should end up being approximately 0.9167

    Thanks! I'd like to ask a question, please! How we use the calculator to calculate the z-score if the probability is given?

    ...And when I saw the table in the stats lecture I thought, yeah right there has got to be a better way, all that messy interpolation. My exams are 8 weeks away and I will become a Jedi Master in this...Presentation wise you are absolutely spot on. I don't know why the heck the tables are needed. Am I going to do the Exam on the same island Tom Hanks was stuck on in Castaway, yeah throw in the abacus while you're at it. lol!

    Got a question, Is there a way to do the function Qnorm in the program R, which shows you percentages before a value?
    For example Qnorm(0.1) is -1.281 because 10% of the area under the graph is before -1.281.
    This is the opposite of p(-1.281) that will give me 0.1.

    Why not just use the Normal C.D function and use the values of the SND? It gives identical answers and I'm assuming I wouldn't lose marks as all the working out is done via calculator anyway.
