This Letter shows quantitatively that the magnitude of the EMC effect measured in electron deep inelastic scattering at intermediate x{sub B}, 0.35{<=}x{sub B{<=}}0.7, is linearly related to the short range correlation (SRC) scale factor obtained from electron inclusive scattering at x{sub B{>=}}1. The observed phenomenological relationship is used to extract the ratio of the deuteron to the free pn pair cross sections and F{sub 2}{sup n}/F{sub 2}{sup p}, the ratio of the free neutron to free proton structure functions. We speculate that the observed correlation is because both the EMC effect and SRC are dominated by the high virtuality (high momentum) nucleons in the nucleus.
