Decision rule for t test

WebWell we can see that our p-value, 0.13, is greater than our alpha value, 0.05. And so because of that, we fail to reject our null hypothesis. And to answer their question, no there is not sufficient evidence to conclude that there is a difference. There's not sufficient evidence to reject the null hypothesis and suggest the alternative. WebT-distributions assume that the null hypothesis is correct for the population from which you draw your random samples. To evaluate how compatible your sample data are with the …

Tests with Two Independent Samples, Continuous Outcome

WebReporting the result of an independent t-test When reporting the result of an independent t-test, you need to include the t -statistic value, the degrees of freedom (df) and the significance value of the test ( p -value). The format of the test result is: t (df) = t -statistic, p = significance value. WebThe test statistic is t = b 0 /se ( b 0) = 576.68/23.47 = 24.57, the value under T-Value. The p -value for the test is p = 0.000 and is given under P-Value. The p -value is actually very small and not exactly 0. The decision rule at the 0.05 significance level is to reject the null hypothesis since our p < 0.05. honey\\u0027s linus giveaway https://amgsgz.com
