The summary statistics of a study between two variables (y and x) is provided below. Interpret the R2 of the regression line based on this data: Sy 9.41 Sx 10.37 R 0.666 107.20 171.14 Question 3 Answer a. for each unit increases in the explanatory variable x, we would expect the response variable y to increase on average by 0.604 b. for the explanatory variable x with the value of 0, the response variable y is expected to be on average 106.39 c. approximately 44% of the variation in the response variable is accounted for by the model (i.e. explained by the explanatory variable)
