WebTo determine whether to reject the null hypothesis using the t-value, compare the t-value to the critical value. The critical value is t α/2, n–p-1, where α is the significance level, n is the number of observations in your sample, and p is the number of predictors.. If the absolute value of the t-value is greater than the critical value, you reject the null … WebMay 12, 2024 · Table of contents. Critical Values for Z. Critical Values for t.

WebMay 31, 2024 · The chi-square (Χ2) distribution table is a reference table that lists chi-square critical values. A chi-square critical value is a threshold for statistical significance for certain hypothesis tests and defines confidence intervals for certain parameters. Chi-square critical values are calculated from chi-square distributions.
WebThe z-score for our apple is (110-100) / 15 = 0.67. The truncated z-table below shows the area for our z-score. By looking at the intersection for 0.6 and 0.07, the z-table indicates that the area under the curve is 0.74857. This value indicates that 74.857% of all apple weights will be lower than our apple weight of 110 grams.
