This video shows how to use the tcdf function on the TI-84 graphing calculator to find the p-value for a hypothesis test using the t distribution.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.Recall, that in the critical values approach to hypothesis testing, you need to set a significance level, α, before computing the critical values, which in turn give rise to critical regions (a.k.a. rejection regions). Formulas for critical values employ the quantile function of t-distribution, i.e., the inverse of the cdf:. Critical value for left-tailed t-test:We will perform the one sample t-test with the following hypotheses: Step 3: Calculate the test statistic t. Step 4: Calculate the p-value of the test statistic t. According to the T Score to P Value Calculator, the p-value associated with t = -3.4817 and degrees of freedom = n-1 = 40-1 = 39 is 0.00149.
