Listed below are the overhead widths (in cm) of seals measured from photographs and the weights (in kg) of the seals. Construct a scatterplot, find the value of the linear correlation coefficient r, and find the critical values of r using α=0.01. Is there sufficient evidence to conclude that there is a linear correlation between overhead widths of seals from photographs and the weights of the seals?

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 48 inches. Is the result close to the actual weight of 198 pounds? Use a significance level of 0.05. Chest size (inches) 58 49 58 43 46 57 355 266 332 177 246 348 Weight (pounds) Click the icon to view the critical values of the Pearson correlation coefficient r. What is the regression equation? y=+x (Round to one decimal place as needed.) What is the best predicted weight of a bear with a chest size of 48 inches? The best predicted weight for a bear with a chest size of 48 inches is pounds. (Round to one decimal place as needed.). Is the result close to the actual weight of 198 pounds? A. This result is exactly the same as the actual weight of the bear. B. This result is not very close to the actual weight of the bear. C. This result is close to the actual weight of the bear. D. This result is very close to the actual weight of the bear. OOO O
