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. WebR function to compute one-sample t-test. To perform one-sample t-test, the R function t.test () can be used as follow: t.test(x, mu = 0, alternative = "two.sided") x: a numeric vector containing your data values. mu: the theoretical mean. Default is 0 but you can change it. alternative: the alternative hypothesis. daughter to mother quotes and poems
