Instructor Tracey Pemberton Ward Cite this lesson In statistics, t-tests can be used to determine if the means of two groups are statistically different. Learn more about how to use and interpret t-tests by reviewing the critical values of the t-Distribution statistical table. ...
Appendix VI: Critical Values of t-DistributionTaghizadegan, Salman
In the t-distribution table, find the column which contains alpha = 0.05 for the two-tailed test. Then, find the row corresponding to 20 degrees of freedom. The truncated t-table below shows the critical t-value. The t-table indicates that the critical values for our test are -2.086 and...
The confidence interval is a probability-based procedure. When we do not know the population standard deviation, we use the t distribution to find the critical value used to calculate the interval. Answer and Explanation: {eq}\begi...
CRITICAL VALUES OF THE F DISTRIBUTION 下载积分: 1500 内容提示: CRITICAL VALUES OF THE F DISTRIBUTION The obtained F is significant at a given level if it is equal to or greater than the value shown in the table. The α=0.05 points on the F distribution are shown in the top row, and ...
Based on the t tables, the critical values of the t-statistic for a two-tailed test with df = 11 and a p level of 0.05 are Blank. A t-test for a mean uses a sample of 15 observations. Find the t-test statistic value that has a P...

Critical values for a test for cointegration are generated based on the joint significance of the levels terms in an error-correction equation. It is shown that the appropriate critical values are higher than those derived from the standard F-distribution. The power properties of this test are co...
