Two independent simple random samples are taken to test the difference between the means of two populations whose variances are
not known, but are assumed to be equal. The sample sizes are n1 = 32 and n2 = 40. The correct distribution to use is the a. t distribution with 73 degrees of freedom
b. t distribution with 72 degrees of freedom
c. t distribution with 71 degrees of freedom
d. t distribution with 70 degrees of freedom
"F" is the name of a function. If we choose "60" as the input to this function, the resulting output vaue is 86. The function F maps 60 (input) onto 86 (output).
