3. A study investigated the cracking strength of reinforced concrete T-beams. Two types of T-beams were used in the experiment, each type having a different flange width. Cracking torsion moments for six beams with 60-cm slab widths and eight beams with 100-cm slab widths are recorded as follows: 60-cm slab width 5.8 10.4 7.2 13.8 9.3 11.5 100-cm slab width 6.9 9.7 7.9 14.6 11.5 10.2 13.7 9.9 Assume the samples are randomly selected from the two populations. Is there evidence of a difference in the variation in the cracking torsion moments of the two types of T-beams? Use a = 0.10.
