Question: The accompanying table lists weights (in pounds) of plastic discarded by a sample of households, along with the sizes of the households. The presence of a correlation implies that we can predict population size by analyzing discarded garbage (information that is important to the Census Bureau). The value of the correlation coefficient r = 0.8424.
| Discarded Plastic (pounds) x | 0.27 | 1.41 | 2.19 | 2.83 | 2.19 | 1.81 | 0.85 | 3.05 |
| Household size y | 2 | 3 | 3 | 6 | 4 | 2 | 1 | 5 |
- Find the regression equation for the above data, and use it to predict the size of a household that discards 0.50 pounds of plastic.
