Assume a twotailed situation at the 005 level of significanc

Assume a two-tailed situation at the 0.05 level of significance has one sample with n=25 and the other has n=27. Use the difference between means test. What is the critical value for t? answer options ------> 2.06 2.678 2.009 2.756

Solution

As n = 25, df - n - 1 = 24.

Thus, a two tailed test at 0.05 significance has critical value of, using table/technology,

tcrit = 2.06 [ANSWER, OPTION A]
