44. Analysis of variance and regression are similar in the sense that

a) They both assume a quantitative response variable

b) They both have F tests for testing that the response variable is statistically independent of the explanatory variable(s)

c) For inferential purposes, they both assume that the response variable l' is normally dis- uibuted with the same standard deviation at all combinations of levels of the explanatory variable(s).

d) They both provide ways of partitioning the variation in Y into "explained" and "unex- plained components.
