WebApr 22, 2024 · 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. WebExpert Answer. Problem Set: Chapter 10 The t Test for Two Independent Samples You conduct an independent-measures t test. Given your null and alternative hypotheses, this is a test. To use the Distributions tool to find the rejection region, you first need to set the degrees of freedom. The degrees of freedom is The critical t-scores that form ...
WebApr 23, 2024 · If the p-value that corresponds to the test statistic t with (n1+n2-1) degrees of freedom is less than your chosen significance level (common choices are 0.10, 0.05, and 0.01) then you can reject the null hypothesis. Two Sample t-test: Assumptions For the results of a two sample t-test to be valid, the following assumptions should be met: WebTo determine whether any significant differences between the subscale mean scores of the two groups was due to an order effect, a two-tailed, independent samples t-test was used.

Typically, you perform this test to determine whether two population means are different. This procedure is an inferential statistical hypothesis test, meaning it uses samples to draw conclusions about populations.
