A Researcher Conducts a Simple Mediated Regression to Determine the Extent

A researcher conducts a simple mediated regression to determine the extent to which reading performance mediates the relationship between time spent on homework and science performance. The researcher finds the following results. Indicate what type of mediation it is (full or partial) and interpret the coefficients for X and M.
