The accompanying table provides data for the sex, age, and weight of bears. For sex, let O 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 25 months of age b. Male bear that is 25 months of age A Click the icon to view the bear measurement data. 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. Weight =D+ O sSex + (O Age (Round to one decimal place as needed.)
