The QualityOfLifeIndex dataset use technology to produce a scatterplot of the two quantitive variables with the regression line on it. If there is a reasonable linear relationship, find a formula for the regression line. Indicate whether there are any outliers in the dataset which might be influential points or have large residuals.
| Country | Norway | Sweden | France | Brazil | Spain | Canada | Australia | Turkey | Japan |
| Life Expectancy | 81.5 | 83 | 81.3 | 74.1 | 78.3 | 82 | 80.1 | 70.5 | 83.4 |
| Material-well-being, thousands of dollars | 74.8 | 50.3 | 37.6 | 8.6 | 25.8 | 43.3 | 49.1 | 9.4 | 32.4 |
The regression line is LifeExpectancy^=73.653+0.155MaterialWellBeing . There are no outliers.
The regression line is LifeExpectancy^=73.653+0.165MaterialWellBeing . There are two outliers for Turkey and Norway.
The regression line is LifeExpectancy^=73.653+0.155MaterialWellBeing . There are three outliers, Turkey, Norway, and Japan.
The regression line is LifeExpectancy^=73.653+0.155MaterialWellBeing . There are two outliers, Turkey and Norway.
The regression line is LifeExpectancy^=73.653+0.165MaterialWellBeing . There are no outliers.
