Here is the DAX measure to display the text result of our paired t-test: Here were using a CR of 95% (or alpha 0.05).As we can see the t-stat 30.30 is much greater than the critical value 8.79 or if we use the p-value approach we can see that the p-value is extremely low and far below the alpha significant level so we reject the null hypothesis in favour of the alternative hypothesis. enter the desired number of licenses, and then select Check out now to complete the transaction. . What is Power BI App? In the upper right corner of the Subscriptions page, select Add subscriptions. The t-stat 30.30 is far greater than the left critical value 5.18 and the p-value is extremely large 1 so without any doubt we fail to reject the null hypothesis.
