TI-83 programs for finite math
These are the text of the programs we are using and a brief description of what they do.
- BIN: This program finds binomial probabilities. You can find the probability of a single event or a sum of many or look at the probability distribution. This is needed in section 8.4
- DRAWNORM: This program takes a left and right X-value endpoint and the mean and standard deviation. It then draws a normal distribution with the area shaded and the probability of being between the endpoints. This is needed in sections 8.5 and 8.6
- LEASTSQR: This program simplifies the calculation of the least squares line. The data is put into L1 and L2 and then when the program is run it will show the data and the least squares line. When you hit ENTER it then gives the equation of the line and the correlation coefficent. This is useful in section 1.5
- NORMAREA: This finds the probability of being between two Z values. Useful in section 8.5 and 8.6
- PIVOTCLN: This program pivot on the element specified on matrix [D]. The data MUST be in matrix [D] to work. This is used in section 4.1.
- ROWOPS: This will perform row operations on a matrix. This is useful in sections 2.2 and 2.3.
- SMPLX: Very similar to PIVOTCLN, except you may choose which matrix has the simplex tableau. Used in section 4.1
