The mean thickness and variance of silicon steel laminations are 0.2 mm and 0.02
respectively. The varnish insulation is applied on both the sides of the laminations. The mean
thickness of one side insulation and its variance are 0.1 mm and 0.01 respectively. If the
transformer core is made using 100 such varnish coated laminations, the mean thickness and
variance of the core respectively are
