WebIn hypothesis testing, critical values are one of the two approaches which allow you to decide whether to retain or reject the null hypothesis. The other approach is to calculate … WebLike all hypothesis testing, the one sample t test determines if there is enough evidence reject the null hypothesis (H0) in favor of an alternative hypothesis (H1). ... The one sample t test calculator assumes it is a two-tailed one sample t test, meaning you are testing for a difference in either direction from the specified value.

Based on the information provided, the significance level is \alpha = 0.01 α = 0.01, and the critical value for a two-tailed test is z_c = 2.58 ...
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 … WebAnd, if the P-value is greater than \(\alpha\), then the null hypothesis is not rejected.

WebApr 23, 2024 · 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 = -1.2508 and degrees of freedom = n 1 +n 2-2 = 40+38-2 = 76 is 0.21484. Step 5: Draw a conclusion. Since this p-value is not less than our significance level α = 0.05, we fail to reject the null hypothesis.
