Thus, we will go ahead and use a t-interval since \(\sigma\) is unknown. Before we can do that however, we need to look up the critical value. To know which row in the t-table to look at, we find the degrees of freedom which is \(n - 1 = 38 - 1 = 37\).Theorem 1 applies here, so we know for certain that this function must have absolute extrema on this domain. f ' ( x) = 2 x, which is zero only at x = 0 and exists at all values of f in [-2, 3]. Therefore, x = 0 is the only critical point of f . The values of f at the endpoints are f (-2) = 4 and f (3) = 9.The simplest formula for a t-test is: Here, x̄ = It is the observed mean, i.e., the sample's mean value. μ = It is the theoretical or population mean, i.e., the population's mean value. s = It is the standard deviation of the sample. n = It is the sample size, i.e., the number of observations in the sample.Aug 4, 2023 · To find critical values on a TI-84 calculator, follow these steps: 1.
