WebFeb 3, 2024 · Excel has one function included in the base program that you can use to help calculate a p-value. To use the function, you can type the formula: =T.TEST (array 1, array 2, tails, type) Where: T.Test is the name of the function Array 1 is the cell range of the first data set Array 2 is the cell range of the second data set WebBecause this is a two-tailed test, we need to find the P-value of a T-value bigger than 0.855 and multiply it by 2. The student's t-distribution is adjusted according to degrees of freedom (df), which is the sample size \((30) - 1 = \underline{29}\) We can find the P-value using a T-table, or with a programming language function:
WebP Value from Z Score Calculator. This is very easy: just stick your Z score in the box marked Z score, select your significance level and whether you're testing a one or two-tailed hypothesis (if you're not sure, go with the defaults), then press the button!

This value can be found by using any T Score to P Value Calculator using t = -0.63374 with 38 degrees of freedom. In this case, p = 0.530047. This is larger than 0.05, so we fail to reject the null hypothesis.
