Question: (continued) 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.
