. It is desired to design 95 confidence intervals for the ratio between standard deviation of two electroplating lines in a micro-electro-mechanical system (MEMS) company. If independent samples of size n1=10 from line-1 has a standard deviation of S1=0.035 mil and sample size of n2=12 from line-2 has a standard deviation of s2=0.062 mil, estimate the confidence intervals for the ratio of standard deviation of line-1 to line-2 (s12/s22)
