Suppose independent random samples that are taken to test the
difference between the means of two populations (n1 = 66 and n2
=46). The variances of the populations are unknown but are assumed
to be unequal. The sample standard deviations are s1=82 and s2=68.
The appropriate distribution to use is the:
A) t distribution with df = 110
B ) t distribution with df = 107
C) t distribution with df = 106
D) F distribution with numerator df =...
