The question asks for the actual number of females, not the proportions (percentages). So firstly, you get the proportions of females with mercury > 145mm, 2.35% + 0.15% = 2.5%. Then, multiply this by the sample size (400) and get the exact count of females which is 2.5% * 400 = 10 females. There you have it!
