Q2. To test the variability of two types of material used in electrical conduits, Strength of the two materials is measured as follow: Year Material A Material B n 25 16 Sample 380 lb 370 lb mean strength Sample 100 400 variance 1. At a=0.2 level. Use the F table to determine The critical points for this two tailed f distribution 2. Assume equal variance, Calculate The pooled variance 3. Calculate the F-ratio
