What's on the worksheet
- Find the missing number among actual, predicted and residual, and say what it means.y = 52,\ \hat{y} = 47y = 18.4,\ \hat{y} = 21.0\hat{y} = 64,\ \text{residual} = -7y = 9.5,\ \text{residual} = 1.5y = 120,\ \text{residual} = -15
- Beach town hotels: read residuals for price against distance from the beach.
- Orchard apples: use harvest by tree age to find and interpret a residual.
- Used bicycles: use the fitted line to find a predicted price and a residual.
- Print shop posters: use the fitted line to find a predicted time and residual.
- Priya's watermelons: answer questions about residuals for a line predicting mass from diameter.
