WebDec 23, 2024 · Imagine you take a sample from X and a sample from Y and you do a t-test for difference between the two. If you repeat this sampling and testing many times, you will find that the t-test returns p > 0.05 in 95% of the cases. I.e. the null has not being rejected 95% of the time and this the "correct" outcome. This simulation in R may help. WebUsing the t-table below notice that:-t(0.975) to t(0.975) with 43 dF equals a range of about -2.02 to 2.02. If the calculated t-value from our example falls within this range then accept … somerhaus event space
