The accompanying table provides data for the sex, age, and weight of bears. For sex, let 0 represent female and let 1 represent male. Letting the response (y) variable represent weight, use dummy variable of sex and the variable of age and to find the multiple regression equation. Use the equation to find the predicted weight of a bear with the characteristics given below. Does s appear to have much of an effect on the weight of a bear? a. Female bear that is 24 months of age b. Male bear that is 24 months of age Click the icon to view the bear measurement data.

Question
Find the multiple regression equation with weight as the response variable and the dummy variable of sex and the variable of age as the explanatory variables.
Transcribed Image Text:The accompanying table provides data for the sex, age, and weight of bears. For sex, let 0 represent female and let 1 represent male. Letting the response (y) variable represent weight, use the
dummy variable of sex and the variable of age and to find the multiple regression equation. Use the equation to find the predicted weight of a bear with the characteristics given below. Does sex
appear to have much of an effect on the weight of a bear?
a. Female bear that is 24 months of age
b. Male bear that is 24 months of age
