How to Find Z-Scores on a TI-84 Plus Sciencing. Sciencing.com Z-scores can be found in a table, but using a TI-84 Plus calculator is easier and more accurate.

11/04/2011 · If I am not mistaken the invT function uses the measure to the left tail. so to do 95% confidence we first do (1-.95) = .05 then we divide it by 2 (equal portion on BOTH tails) so we have .025.... The keypad on the TI{83 Plus is almost identical to the original TI{83. On the TI{83 Plus there is a new, purple APPS key, the MATRXmenu is a 2nd (yellow, or secondary) function, and the FINANCEpackage is …

Z-Test( performs a z significance test of a null hypothesis you supply. This test is valid for simple random samples from a population with a known standard deviation. In addition, either the population must be normally distributed, or the sample size has to be sufficiently large.... Use the TI-83 calculator to test the hypothesis that the population mean is greater than 100 with a level of significance of a = 5%. Solution: “The population mean is greater than 100” means the alternate hypothesis is H 1 : m > 100, and the null hypothesis is H 0 : m £ 100.

But a z-score literally just means how many standard deviations you are away from the mean. It could apply to any distribution that you could calculate a mean and a standard deviation for. So E is not the correct answer. A z-score can apply to a non-normal distribution. So the answer is C. And I guess that's a good point of clarification to get out of the way. And I thought I would do two

### How to Find Z-Scores on a TI-84 Plus Sciencing. Sciencing.com Z-scores can be found in a table, but using a TI-84 Plus calculator is easier and more accurate.

- Sciencing.com Z-scores can be found in a table, but using a TI-84 Plus calculator is easier and more accurate. There are two methods of finding the z-score of a data set: you can use the TI-84 Plus to find the mean and standard deviation and then use the z-score equation, or you can use the TI-84 Plus invNorm function with a percentile as the argument.
- we will round the z-test statistic to 4 decimal places and the P-value to 3 significant figures; these are the same rounding rules your TI-83/84 calculator typically uses in Draw mode.
