Given the information: n1= 50, n2=50, s21=8, s2 2=14 and assuming that the population variances are unequal, then the degrees of freedom that should be used with the test statistic is: 98 94 45 91
Added by Jose Maria D.
Step 1
Step 1: Calculate the degrees of freedom using the formula for unequal variances: df = ((s21/n1 + s22/n2)^2) / (((s21^2)/(n1^2*(n1-1))) + ((s22^2)/(n2^2*(n2-1)))) Show more…

Assuming equal population variances, determine the number of degrees of freedom for the following: n1 = 16, s1^2 = 25; n2 = 20, and s2^2 = 30.
Ahmet Y.
Suppose that s12 = 4, s22 = 6, n1 = 15, n2 = 25 and assume that the population variances are equal. The number of degrees of freedom that should be used in a t-test of two population means is:
