In comparing the two standard deviations below what test val

In comparing the two standard deviations below, what test value and degrees should be used in an F test ? Test value= 3.00; d.f. N= 13 and d.f. D. = 27 test value= 3.00; d.f.N. = 26 and d.f.D= 12 test value= 9.00; d.f.N= 27 and d.f.D. = 13 test value = 9.00; d.f.N= 12 and d.f.D. = 26 6 squirrels were found to have an average weight of 8.5 ounce with a sample deviation is 0.9. Find the 95 percentage confidence interval of the true mean weight. 7.6 lesser than mu lesser than 9.4 6.2 lesser than mu lesser than 10.8 7.8 lesser than mu lesser than 9.2
