How do I fix invalid dimensions


You're probably trying to graph a function that does not involve stat plot features. You can correct this by turning off the stat plot features. Press "2ND" "STAT PLOT" and then select 4:PlotsOff.

If you're not trying to graph a function, please tell us exactly what you are trying to do when you get this error.

What info does f'' give about a graph f. Draw y= 1/x - 1/x2 (=(x-1)/x2)


Hello,
The second derivative indicates the rate of variation of the first derivative. Each point where the second derivative vanishes (has value 0) is an inflexion point of the curve.

Yes you can use it, here is the formula: Y= V(t+ (i/c))^(tc) V=amount put in, t=time, i=intrest rate, c= amount of times it is compounded.
(I know this because I have a TI-83 calculator)

Need to no how to find Type 1 error for statistics on TI 83 plus


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.
