Let X - N(ux, o3) and Y N(Hy,ož) where all parameters are not known. We would like to know if it is reasonable to assume that ož = o3. From 6 observations of X, we calculate a sample mean of 0.31 and a sample variance of 0.0526. From 8 observations of Y, we calculate a sample mean of 4.97 and a sample variance of alitu of th 0 O613 bunoth
