Question

The given information is available for two samples selected from independent normally distributed populations.

Population A: ny = 16, s, = 169.3 Population B: n = 16, S = 137.5
How many degrees of freedom are there in the numerator and denominator of the F test?

Answer 1

The degrees of freedom in the numerator is ny - 1 and in the denominator is n - 1 in the F-test comparing two independent populations.

Step-by-step explanation:

The F-test compares the variances of two independent populations. In this case, we have two samples - Population A and Population B. The degrees of freedom in the numerator is equal to the sample size of Population A minus 1 (ny - 1). The degrees of freedom in the denominator is equal to the sample size of Population B minus 1 (n - 1).
