d Week 7 Question 9, 10.1.2 HW Score: 0%, 0 of 28 points Points: 0 of 1 Save Twenty different statistics students are randomly selected. For each of them, their body temperature ( C) is measured K and their head circumference (cm) is measured. If it is found that r = 0, does that indicate that there is no association betwen these two variables? Choose the correct answer below. O A. Yes, because if r = 0, the variables are completely unrelated. O B. No, because while there is no linear correlation, there may be a relationship that is not linear. O C. No, because r does not measure the strength of the relationship, only its direction. O D. No, because if r = 0, the variables are in a perfect linear relationship.

Results are shown in the accompanying Correlation coeff, r: 0.969427 display. Is there sufficient evidence to support the claim that there is a linear correlation between the weights of bears and their chest sizes? When Critical r: +0.2680855 measuring an anesthetized bear, is it easier to measure chest size than weight? P-value (two tailed): 0.000 If so, does it appear that a measured chest size can be used to predict the weight? Use a significance level of a = 0.05. . . .
