Question

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 bear with a chest size of 51 inches. Is the result close to the actual weight of 342 pounds? Use a significance level of 0.05. click the icon to view the critical values of the correlation coefficient. What s the regression equation? y^cap = (Round to one decimal place needed) Whet is the best predicted weight of a bear with a chest size of 51 inches? y^cap = pounds (Round 10 are decimal place as needed.) Is the result close to the actual weight of 342 pounds? A. This result is exactly the same as the actual weight of bear. B. This result is not very close to the actual weight of the bear. C. This result is very close to the actual weight of the bear. D. This result is close to the actual weight of the bear.

Explanation / Answer

Using excel data tool

a) y = -172.6+11.1x

b) Y = -172.6+11.1*51 = 392.4

c) Option B is Correct

Intercept -172.6 162.184 -1.06449 0.347098 X Variable 1 11.1 3.402669 3.25633 0.031189
