Groups Measurements $G_1$: 11, 12, 15 $G_2$: 14, 18, 21 $G_3$: 23, 29, 31 $G_4$: 29, 30, 36 (a) How many different samples can arise with this sampling scheme? (b) If $\bar{y}$ is the equally weighted mean of the 6 sample observations, write down the sampling distribution of $\bar{y}$. (c) Show that $\bar{y}$ is unbiased for $Y$. (d) Calculate $Var(\bar{y})$. 11.3.3 Referring to Exercise 11.3.2 if the groups are rearranged as shown in the table below, redo parts (a), (b), (c) and (d) for the new groups. Explain the difference in $Var(\bar{y})$ for the two different arrangements. $G_1$: 11, 18, 31 $G_2$: 12, 21, 29 $G_3$: 15, 23, 30 $G_4$: 14, 29, 36
