Question
Instructions: Use the technology of your choice (calculator, Excel, GeoGebra, Google Sheets) to find the regression line, the
Data Set: {(0,7),(1,5),(1.5,3),(2,5),(2.3,3.2),(3,2),(3.5,4)}{(0,7),(1,5),(1.5,3),(2,5),(2.3,3.2),(3,2),(3.5,4)}
- The regression line is: y=y= Answer −− Answer xx
- Based on the regression line, we would
expect the value of response variable to be Answer when the explanatory variable is 0. (NOTE: This is the yy-intercept.) - For each increase of 1 in of the explanatory variable, we can expect a(n) Answerdecreaseincrease of Answer in the response variable. (NOTE: This is the slope.)
- If x=2.5x=2.5, the yˆ=y^= Answer. This is an example of Answerextrapolationinterpolation.
- The correlation coefficient is r=r= Answer.
