WebTherefore, it seems reasonable to use the test statistic: T = X ¯ − μ 0 S / n. for testing the null hypothesis H 0: μ = μ 0 against any of the possible alternative hypotheses H A: μ ≠ μ 0, H … WebFind the P-Value. The next step is to find the p-value for the test statistic. A p-value is used to determine whether to reject the null hypothesis.. Use a t-table and locate the degrees of freedom in the left-most column. Then, locate the desired p-value in the heading row, 0.05 is most commonly used for a 95% confidence level. highest common factor hcf of 75 and 90
