(7) Question 7. Suppose we have the same population information as given in the statement before Question 1. If $\left\ {X_{1}, \cdots, X_{n} ight\}$ are the measurements of a random sample of objects drawn WITHOUT replacement from this population, and if $\sigma^{2}=40, N=50$, and the value of $V (\bar{X})=60 / 49$, what is the sample size $n$ ? (a) $n=33$ (b) $n=20$ (c) $n=16$ (d) $n=24$. (e) The value of $V(\bar{X})$ cannot be $60 / 49$, so the problem is not solvable as stated. (f) The sample size cannot be determined from the given information. (g) None bf the above. SS.SP.287
