[Total: 1 + 1 + 2 = 4 marks] A different research project is undertaken on animal brain activity. The following table shows the body weight and brain weight of seven different animals. a. Calculate r, Pearson’s correlation coefficient, for the given data, correct to 2 decimal places. Answer 1 Question 7[input] b. If we assume the relationship between body weight and brain weight is linear, what does the value in part a indicate about the strength of the relationship? Answer 2 Question 7[select: , It indicates a weak relationship between the given variables, It indicates a strong relationship between the given variables, It indicates no relationship between the given variables] The regression equation which relates body weight to brain weight is given as Brain weight = 0.000986 × Body weight + 0.0923 The body weight of a wolf is 36 kg. c. Use your regression equation to estimate the brain weight of a wolf in kg, correct to 3 decimal places by completing the following calculation. Brain Weight = 0.000986 × Answer 3 Question 7[input] + 0.0923 = Answer 4 Question 7[input]kg
