What are the degrees of freedom and critical values for independent samples t-tests with = 0.05; two-tailed; n1 = 10, n2= 10 Please write your critical value answer in the following format: (for a 2 tailed test) 1.234 and -1.234 (for a one tailed test) 1.234 or -1.234
Added by Ethan M.
Step 1
Degrees of freedom = (n1 + n2) - 2 Degrees of freedom = (10 + 10) - 2 Degrees of freedom = 20 - 2 Degrees of freedom = 18 ** Show more…

(a) Determine the critical value for a right-tailed test of a population mean at the $\alpha=0.01$ level of significance with 15 degrees of freedom. (b) Determine the critical value for a left-tailed test of a population mean at the $\alpha=0.05$ level of significance based on a sample size of $n=20$ (c) Determine the critical values for a two-tailed test of a population mean at the $\alpha=0.05$ level of significance based on a sample size of $n=13$
