WebJan 22, 2024 · To test if the slope coefficient is statistically significant, we can calculate the t-test statistic as: t = b 1 / se(b 1) t = 2.7037 / 0.7456; t = 3.626; The p-value that corresponds to this t-test statistic is shown in the column called Pr(> t ) in the output. The p-value turns out to be 0.00464. WebTo perform Paired t-test in R, we have to set paired argument TRUE and run the test again with the same formula and dataset. t.test (uptake ~ Treatment, paired = TRUE, data = …
