There are t-tables that show values for one-tailed and two-tailed tests. Since the test is right-tailed, this is a one-tailed test. If n = 21, degrees of freedom would be n - 1, which is 20. (I'm assuming this was a one-sample t-test. If not, the degrees of freedom would be different for two-sample t-tests.) Look for the t-test statistic in the table with the above information to determine the p-value (which is the actual level of the test statistic).
I hope this will help.
use technology to find the P-value for a right-tailed test with n=21 and test statistic t=2.065
apparently, i don't have a stat calculator or statistical software to use to find the answer. so i need help how to find it by using the t distribution table..
