Okay, so, two sample dependent t test. So two samples are paired t test is to test the mean of two samples that depend on each other. So we can create a data set. You can use a T test data variable one data variable to pay equal to true. So let's say our T test data variable one, data variable two Pat equal to true China formula data available and data available to pay equal to true okay then a semicolon. So, the p value Lisa pipeline tray seven nine e to power minus or a.

So we can do as a result. So, for the t test p value is 5.379 e to the power minus zero E. So, for to sample Patty test now hypothesis is the mean of the first variable in other data minus the mean of the second data. Second data equal to zero alternate hypothesis is the mean of First Data minus the mean of our second data Okay not equal to zero. So, the p value is 5.379 e to the power minus A hands the p value is less than 0.05, which is the alpha value. Therefore, the null hypothesis may be rejected. So we can reject this essay now hypothesis, sociability so we can reject this null hypothesis.

So, the alternate hypothesis is that the mean of the tower ha mean on the first data minus the mean of the second data not equal to zero. So, we reject the null hypothesis and the data alternate hypothesis
