also, I think the z-score formula looks a lot like the formula for a derivative in limit form with z being in respect to the derivative, and h = to the std dev
so i did the first part and got the sample statistics, but I dont remember which formula to use to compare them. and I know they are giving me part of the variables and expecting me to do it backward a bit to find the missing part
its very simple, it is a 'based on the mean and variance of a set of samples' and given a population std dev, is a stated mean for the population acceptable within a=0.05
so, I have a post-frame shed, 12x16. there are posts at 6' on the short sides and every 4' on the long side. posts are set ~18" below grade, on a 2" cap of cement over a few inches of well compacted gravel, holes were all about 27" or so, 2x6 girder runs level at the top (very level all the way a...
anyway, point is, I think a 5.5" slab, which is on some spongy clay with probably be fine, since its a 12x16' shed. avoid the gravel, the trouble, the labor, time etc with putting a couple inches of gravel in a shed
ok, so, basically I have ~5.5" to grade from bottom of 2x6 girder to top of board, and the Ive got posts set in concrete, at 24" from the top of that board

I dont really, and clearly I need to put something togteher so I will have enough academic/intellectual merit to actually get my company/education funded (because that does count)
i put together and did the opening ceremony at a Phi Theta Kappa inauguration, donated stuff for a affle and to the Joplin tornado survivors, i went to our regionals at K State for the weekend
