The Sampling Distribution of the Ratio of Two Sample Variances $S _ { 1 } ^ { 2 }$

question 27

Short Answer

The sampling distribution of the ratio of two sample variances $S _ { 1 } ^ { 2 }$ / $s _ { 2 } ^ { 2 }$ is said to be F-distributed provided that: $\begin{array}{|l|l|}\hline A.&\text { the samples are independent.}\\\hline B.&\text {the populations are normal with equal variances.}\\\hline C.&\text {the samples are dependent and their sizes are large. }\\\hline D.&\text { the samples are independently drawn from two normal populations.}\\\hline \end{array}$
