Unformatted text preview: Does COST appear to be linearly related to CATTLE? d. Plot the residuals versus predicted values. Do see a random scattering of points? Are there apparent outliers? e. Remove apparent outliers and re-work parts a. and b. How did the results change? 2. a. Use the analysis based on the entire data set. Compute the predicted cost of operation for each market based on the model equation. b. Plot a band of 95% confidence intervals for the expected cost of operation of all markets. How many observed cost values are in the intervals? c. Plot a band of 95% prediction intervals for the cost of operation of individual markets. How many observed cost values are in the intervals?...
