Question

A show work ! The data show the chest size and weight of several bears. Find the regression equation, letting chest size be the independent (x) variable. Then find the best predicted weight of a be of 58 inches. Is the result close to the actual weight of 562 pounds? Use a significance level of 0.05.

What is the best predicted weight of a bear with a chest size of 58 inches? y = Lpounds (Round to one decimal place as needed ) Is the result close to the actual weight of 562 pounds? 0 A. This result is very close to the actual weight of the bear O B. This result is exactly the same as the actual weight of the bear c. This result is close to the actual weight of the bear 0 D. This result is not very close to the actual weight of the bear Click to select your answer(s)
