Step 1

Given that two populations have equal population variances but different have different sizes N1 = 100000 N2 = 10000000.  A sample of size n= 25 is selected.

The relationship between population variance (σ2) and sample variance (S2 ) is shown below. n is the sample size.

Step 2

Since here the sample size is same in both samples drawn from two populations and bot...
