1. anyone want to help me with some stats work...?

"Find the 1 percentile of the standard Normal distribution to (at least) 2 decimal places. "

wtf??

"X stands for the Normal random variable with mean 5 and standard deviation 3.

Find:
P( X < 12.17 )
P( X > 12.68 )
P( -2.59 < X < 6.44 )
P( X < 1.88 or X > 8.12 )"

the first one to give the correct answers and sit the test for me gets a lollipop...

My excel looks a tad better than that - time to upgrade me thinks

6. download SPSS for windows and just give in the info, one click on a button and you have a nice diagram, and even a boxplot if you like

I don&#39;t think you should use a Gauss-curve here by the way, but you better ask someone else, because I&#39;m not too good at math (maybe if you ask Lamsey nicely he&#39;ll help you out a bit )

myself and tc were trying today, but i think we asked him a little too much and annoyed him...

it might be cos i stole his hat, or beat him at pool or something, i&#39;m not sure

anyway, thanks for the help guys, i still failed the test though

edit: lmfao...i just checked there and i actually passed

i just assumed i was gonna fail
