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.
