If \( G \) is the \( G M \) of the product of \( r \) sets of
\( \mathrm{P} \) observations with geometric means \( G_{1}, G_{2}, \ldots G_{r} \)

W respectively, then \( G \) is equal to
(1) \( \log G_{1}+\log G_{2}+\ldots+\log G_{r} \)
(2) \( G_{1} \cdot G_{2} \cdot \ldots \cdot G_{r} \)
(3) \( \log G_{1} \cdot \log G_{2} \ldots \log G_{r} \)
(4) None of these
