8. Se realizó un experimento para determinar si era posible predecir el peso de un animal despues de un periodo determinado con base en su peso inicial y la cantidad de alimento que consumía. Se registraron los siguientes datos, en kilogramos: Peso final 95 77 80 100 97 70 50 80 92 84 Peso inicial 42 33 33 45 39 36 32 41 40 38 Peso del alimento 272. 226 259 292 311 183 173 236 230 235 a) Ajuste una ecuación de regresión múltiple. b) Prediga cuánto pesará un animal que comienza pesando 35 kilogramos después de consumir 250 kilogramos de alimento.

An experiment was conducted to determine if the weight of an animal can be predicted after a given period of time on the basis of the initial weight of the animal and the amount of feed that was eaten. The following data, measured in kilograms, were recorded: \begin{tabular}{ccc} Final Weight, $y$ & Initial Weight, $x_{1}$ & Feed Weight, $\boldsymbol{x}_{2}$ \\ \hline 95 & 42 & 272 \\ 77 & 33 & 226 \\ 80 & 33 & 259 \\ 100 & 45 & 292 \\ 97 & 39 & 311 \end{tabular}.(a) \begin{tabular}{ccc} Final Weight, $y$ & Initial Weight, $x_{1}$ & Feed Weight, $x_{2}$ \\ \hline 70 & 36 & 183 \\ 50 & 32 & 173 \\ 80 & 41 & 236 \\ 92 & 40 & 230 \\ 84 & 38 & 235 \\ Fit a multiple regression equation of the form \end{tabular} $\mu_{Y \mid x_{1}, n_{n}=}=00+\beta_{1} x_{1}+\beta_{2} x_{2}$ (b) Predict the final weight of an animal having an initial weight of 35 kilograms that is fed 250 kilograms.

An experiment was conducted to determine if the weight (y) of an animal can be predicted after a given period of time on the basis of the initial weight (x1) and the amount of feed (x2) that was eaten. Final Weight (Kg) (y): 95, 77, 80, 100, 97 Initial Weight (Kg) (x1): 42, 33, 33, 45, 39 Feed amount (Kg) (x2): 272, 226, 259, 292, 311 a. Fit a multiple regression equation of the form ŷ = b0 + b1x1 + b2x2 b. Predict the final weight of an animal having an initial weight of 35 kilograms that is given 250 kilograms of feed.

Sam enters data for weight (in pounds) and weekly food cost (in dollars) of pets into a statistics software package and finds a regression equation of Å· = 0.3 + 0.12x, where weight is the explanatory variable. Based on this information, select Sam's conclusion about food weight and costs that is TRUE. a.) For each additional pound of weight, weekly food costs stay relatively the same. b.) For each additional pound of weight, weekly food costs decrease by 12 cents. c.) For each additional pound of weight, weekly food costs increase by 12 cents. d.) For each additional pound of weight, weekly food costs increase by 30 cents.
