Incorrect Question 10 0/ 1 pts Using GSS2006 data, we investigate the relationship between education and concern over global warming (concern is measured in a scale from 0=not concerned, up to 15=great concern). We think that support for science (measured on a scale from 0=no support, up to 9=full support) could play a mediating role in this. We get the following arrows and betas for a path model (all betas are statistically significant): Beta for arrow from education to science support: +.25 Beta for arrow from education to global warming concern: +. 10 Beta for arrow from science support to global warming concern: +. 15 What percentage of the total effect is direct? 0.1 0.2 .0.37 0.71
