Question

Score:UUIIL TUUL 13 19 Cumpele 9.3.42 In a one-tail hypothesis test where you reject Hy only in the upper tail, what is the critical value of the t-test statistic with 74 degrees of freedom at the 0.01 level of significance? Click to view the first page of the table of critical values of t. Click to view the second page of the table of critical values of t. The critical value of the t-test statistic is l. (Round to four decimal places as needed.)

Answer 1

Solution

Given that, the test is Upper tailed one sided i.e Right tailed test.

Degrees of freedom = d.f = 74

$\alpha$ = 0.01

For the right tailed test , the critical value is $t_{\alpha,d.f.}$

$t_{\alpha,d.f.}$ =  $t_{74,0.01}$ = 2.3778
