Question about Texas Instruments TI-83+ Graphing Calculator (TEX83PL)

Please help!

Carry out the test. The calculator will display a p= value (or if you draw it - it will be the shaded area). This is the type one error. Why? Well if H0 is true then your t-test will come from this distribution. Think of the bell shape as a histogram - you have one value you are comparing to it. Is this value typical of this "histogram"? If the value is near the centre of the bell it is reasonable that it came from it. If it is in the extreme it probably didn't and so we reject H0. The type one error is the probability that we reject H0 given that it is true. H0 assumes the t value comes from this distribution - so it is the probability of getting this value or something more extreme. (i.e. the shaded area. Incidently this is the same way of finding the type one error for any test.

If some of the lists are missing press the STAT button then select SetUpEditor and ENTER to restore all of them (without data, of course.)

If the statistical plots are turned OFF you can turn one of them back ON again. Press SHIFT Y1= to access STAT PLOTS. Press 4:Plots Off. A good habit to avoid problems. After you turn all plots OFF, you must turn one of them ON if you intend to draw statistical graphs. You can for example Turn Plot1 ON.

Press SHIFT 0 to enter catalog. Press x^-1 key to jump to the first command that starts with D.

Scroll down to reach DiagnosticsON, highlight it and press ENTER then ENTER.

You can't simply enter 7x+9=30 into the calculator, there is a way to calculate what the x is but its been a few years since I've done these..

you mean edit - just do 2nd , then window, walla - use your arrows to navigate and reset numbers, sometimes you need the table setup for the statistic and probability calculations - get the ti for dummies, and there is a statistics ti 84 book also that helps a lot.
