  We analyze the MiniBooNE CCQE $d\sigma/dT_\mu d\cos\theta_\mu$ data using a
theoretical model that has proved to be quite successful in the analysis of
nuclear reactions with electron, photon and pion probes. We find that RPA and
multinucleon knockout turn out to be essential for the description of the
MiniBooNE data. We show these measurements are fully compatible with former
determinations of nucleon axial mass $M_A$, in contrast with several previous
analyses, which have suggested an anomalously large value. We find, $M_A=1.08
\pm 0.03$ GeV. We also argue that the procedure, commonly used to reconstruct
the neutrino energy for QE events from the muon angle and energy, could be
unreliable for a wide region of the phase space, due to the large importance of
multinucleon events.
