A research assistant is asked to draw two independent normally distributed samples. The first sample, X has a 10 observations with a mean of 1 and sample variance of 2. The second sample. Y has 20 observations with a mean of 0.5 and a sample variance of 3. Test the following hypotheses: (a) X = Y (b) X > Y (c) Var (X) = Var(Y) (d) Var (X) = 1.5 (e) Var (Y) = 2.5 A research assistant is asked to draw two independent normally distributed samples.
