Regarding the standard error of the estimate,
a. give two interpretations of it.
b. identify another name used for it, and explain the rationale for that name.
c. which one of the three sums of squares figures in its computation?
14.7 The difference between an observed value and a predicted value of the response variable is called a________
In Exercises 14.12-14.21, we repeat the data and provide the sample regression equations for Exercises 4.48 -4.57.
a. Determine the standard error of the estimate.
b. Construct a residual plot.
c. Construct a normal probability plot of the residuals.
Plant Emissions. Use the data on plant weight and quantity of volatile emissions from Exercise 14.25.
a. compute the standard error of the estimate and interpret your answer
b. interpret your result from part (a) if the assumptions for regression inferences hold.
c. obtain a residual plot and a normal probability plot of the residuals.
d. decide whether you can reasonably consider Assumptionsfor regression inferences to be met by the variables under consideration. (The answer here is subjective, especially in view of the extremely small sample sizes.)
