Finding P-values TI-84 Instructions. Right Tailed t-test: Calculate t_calc (t_test) 2nd DISTR. Scroll down to tcdf(. ENTER. Now enter: t_calc, 1000, df) ENTER. Output is the P-value.
Another way to find the p-value for a given t statistic is to use a graphing calculator like a TI-83 or TI-84. On your calculator, click 2ND VARS (to get to DISTR), scroll down, and click the tcdf function. The syntax to use this function to find the p-value for a right-tailed test is as follows:
This video shows how to use the tcdf function on the TI-84 graphing calculator to find the p-value for a hypothesis test using the t distribution.
The p-value helps to determine the significance of your results by comparing them to a chosen significance level. In this article, we will guide you through the process of calculating the p-value on your TI-84 calculator.
How do I calculate the p-value on a TI-83 Plus family, TI-84 Plus C Silver Edition, TI-84 Plus family, or TI-Nspire in TI-84 Plus mode? First the TI-83 Plus family, TI-84 Plus family, or TI-Nspire in TI-84 Plus mode will compute all the one-variable statistics (mean of x, s , n, etc.).
This video shows how to use the tcdf function on the TI-84 to calculate the p-value for a hypothesis test.
The p-value would be P(z >1.85) or the area under the standard normal curve to the right of z = 1.85. The p-value would the area to the right of 1.85 on the z-table. Notice that the p-value is .0322, or P(z > 1.85) = .0322. We could find this value directly using Normalcdf(1.85,10).
Use the given information to find the P-value. Also, use a 0.05 significance level and state the conclusion aboutthe null hypothesis (reject the null hypothe...
How to Find the P-Value in a TI-84: A Step-by-Step Guide. To find the p-value using a TI-84 calculator, follow these steps: 1. Enter the data: Input the dataset into the calculator. Make sure the data is properly stored in a list or matrix. 2. Conduct the hypothesis test: Execute the relevant test, depending on the type of hypothesis you are ...
How do I find the p-value on a TI-84 calculator? To find the p-value on a TI-84 calculator, you need to use the “invNorm” function. This function allows you to calculate the p-value based on the sample mean, standard deviation, and sample size.
