We present a statistical analysis of the Kepler M dwarf planet hosts, with aparticular focus on the fractional number of systems hosting multipletransiting planets. We manufacture synthetic planetary systems within a rangeof planet multiplicity and mutual inclination for comparison to the Kepleryield. We recover the observed number of systems containing between 2 and 5transiting planets if every M dwarf hosts 6.1+/-1.9 planets with typical mutualinclinations of 2.0 +4.0-2.0 degrees. This range includes the Solar System inits coplanarity and multiplicity. However, similar to studies of Keplerexoplanetary systems around more massive stars, we report that the number ofsingly-transiting planets found by Kepler is too high to be consistent with asingle population of multi-planet systems: a finding that cannot be attributedto selection biases. To account for the excess singleton planetary systems weadopt a mixture model and find that 55 +23-12% of planetary systems are eithersingle or contain multiple planets with large mutual inclinations. Thus, wefind that the so-called "Kepler dichotomy" holds for planets orbiting M dwarfsas well as Sun-like stars. Additionally, we compare stellar properties of thehosts to single and multiple transiting planets. For the brightest subset ofstars in our sample we find intriguing, yet marginally significant evidencethat stars hosting multiply-transiting systems are rotating more quickly, arecloser to the midplane of the Milky Way, and are comparatively metal poor. Thispreliminary finding warrants further investigation.
