Web11 sep. 2024 · 16.4: Critical Values for t-Test. Assuming we have calculated texp, there are two approaches to interpreting a t -test. In the first approach we choose a value of α for rejecting the null hypothesis and read the value of t(α, ν) from the table below. If texp > t(α, ν), we reject the null hypothesis and accept the alternative hypothesis. Webp = signrank (x,y) returns the p -value of a paired, two-sided test for the null hypothesis that x – y comes from a distribution with zero median. p = signrank (x,y,Name,Value) returns the p -value for the sign test with additional options specified by one or more Name, Value pair arguments.
