Nope, the TI-30XA is a one variable stat calculator.

Two variable stat is done OK by TI-36X or TI-30X IIS, also comparable HP or Casios

There is nothing for directly solving cubics, but the general purpose Solver() function can be used for this. For example, given the cubic x^3+x^2=125 with a guess at a root at 4, Solver(x^3+x^2=125,x,4) will produce an answer of about 4.64. Full details are in the manual in the "Equation Solving" chapter.

The chi-square test is used for a lot more than just contingency tables.

I found one program for the TI-86 (which is basically the same machine as the TI-85, only with more memory) which claims to do the chi-square goodness of fit test.

### When i press the graph button on my ti-85 nothing happens

You might want to check the settings on your calculator. For example, make sure the axis (x and y) are shown and not kept invisible. And make sure that you have a typed an equation into the calculator as well. Hope this helps.

### If I enter the following equation: 1/9+1-1-1/9 my calculator displays -1E-14 but the answer is 0. Please, explain

This is because the TI-85, like any other calculator, is a finite device and 1/9 cannot be represented exactly in decimal notation.

For this discussion I'm going to use five digits instead of fouteen so it's easier to see.

1/9 = .11111

+1 = 1.1111 (note one digit falls off the right end)

-1 = .1111 (the missing digit doesn't come back)

-1/9 = -.00001

### Put in anova stuff have three lines of numbers L1 L2 L3 then anova then error

Hi,
It looks like the calculator performed well, because it found what you asked for and gave you an estimate of the error. It is up to you to interpret the results. The error screen you got is part of the process (normal behavior). The calculator is not at fault.

Hope it helps.

### Does the TI 30 have the 1/n on key? If so, where is the key or what are the steps to perform a 1/n equation?

Hi,
To perform 1/n equation you'll have to use "A b/c" button between the numerator and the denominator numbers as shown in the attached image:
