Test the claim that populations A and B have different variances. Suppose that the populations are basically distributed. Suppose that the two samples are independent and that they've been randomly chosen. Use a significance level of 0.10.
Sample A: n=28, x1(with line above x)= 19.2, s=4.7
Sample B: n=41, x1(with line above x)= 23.7, s=5.89
