A researcher is investigating the relationship between economic
development (x) and level of religiosity (y) in ten countries. (The
researcher has interval-level measurements for both variables.)The

than will citizens of countries at the higher end of the
development scale. As development increases, religiosity decreases.
Draw and Label four sets of axes, like this one below:
(A.) Is the researcher hypothesizing...
