Extracted text: essary.) Data Set: {(0, 7), (1, 5), (1.5, 3), (2, 5), (2.3, 3.2), (3, 2), (3.5, 4)} 1. The regression line is: y = 2. Based on the regression line, we would expect the value of response variable to be when the explanatory variable is 0. (NOTE: This is the y-intercept.) 3. For each increase of 1 in of the explanatory variable, we can expect a(n) + of in the response variable. (NOTE: This is the slope.) 4. If x = 2.5, the ŷ . This is an example of %3D 5. The correlation coefficient is r =
