Abstract
We use 28 Hubble parameter, , measurements at intermediate redshifts to determine the present-day Hubble constant in four cosmological models. We measure and km s Mpc (1 errors) in the CDM (spatially flat and non-flat), CDM and CDM models, respectively. These measured values are more consistent with the lower values determined from recent cosmic microwave background and baryon acoustic oscillation data, as well as with that found from a median statistics analysis of Huchra's compilation of measurements,but include the higher local measurements of within the 2 confidence limits.
