In order to probe the factorization hypothesis in the color-suppressed decays B→ψ(2S)+K(K*) we have studied three ratios R≡B(B→ψK)/B(B→ψ(2S)K), R′≡B(B→ψK*)/B(B→ψ(2S)K*), and ${\mathrm{P}}_{\mathrm{L}}^{\prime }$≡${\mathrm{\Gamma }}_{\mathrm{L}}$(B→ψ(2S)K*)/Γ(B→ψ(2S)K*) in several scenarios for the ${\mathrm{q}}^2$ dependence of the form factors involved. We find that measurements of R and R′, which exist, do not yield scenario-independent tests of factorization. However, the predicted range of ${\mathrm{P}}_{\mathrm{L}}^{\prime }$ in all scenarios lies in a narrow range, 0.50≲${\mathrm{P}}_{\mathrm{L}}^{\prime }$⩽0.67, and could test factorization.
