a. Explanation Given info: The data shows that Job performance under time pressure, and the complete second order model is y ^ = β 0 + β 1 x 1 + β 2 x 1 2 + β 3 x 2 + β 4 x 1 x 2 + β 5 x 1 2 x 2 . Calculation: The equation for E ( y ) as a function of x 1 , when the team leader is not effective. Substitute x 2 = 0 for x 2 in the complete second order model. The equation is y ^ = β 0 + β 1 x 1 + β 2 x 1 2 + b. To determine To Write: The equation for E ( y ) as a function of x 1 , when the team leader is effective. c. To determine To sketch: The two equations of part ( a ) and part ( b ) . To explain: The nature of the curvilinear relationship.

Mice can be a serious public health issue, as they can carry disease and parasites. It is important to track their feeding and living spaces. The accompanying data are a subset of data from a scatterplot that appeared in the paper "Small Mammal Responses to Fine Woody Debris and Forest Fuel Reduction in Southwest Oregon."+ The authors of the paper were interested in how the distance a deer mouse will travel for food is related to the distance from the food to the nearest pile of fine woody debris. Distances were measured in meters. Distance from Debris in Meters (x) 6.94 m 5.23 5.21 7.10 8.16 5.50 9.19 9.05 9.36 Distance Traveled in Meters (y) 0.00 6.13 11.29 14.35 12.03 22.72 20.11 26.16 30.65 The equation of the regression line is ŷ = -7.69 + 3.23x. How far (in m) would we predict a mouse to travel for food if the distance from a pile of debris is 7.49 m? (Round your answer to two decimal places.)
