Below the graph you will see a box labeled, “t Test”. The test statistic is called the t Ratio. For this test, its value is 1.831802, below that is the degrees of freedom, which is calculated as the number of observations – 2. Since our file contained 22 observations, DF = 20 in this case. Finally, you can find the p value is equal to 0.0819. ................
