Correlation Results Fifty-four wild bears were anesthetized, and then their weights and chest sizes were measured and listed in a data set. Results are shown in the accompanying display. Is there sufficient evidence to support the claim that there is a linear correlation between Correlation coeff. r: l0,969937 the weights of bears and their chest sizes? When measuring an anesthetized bear, is it easier to measure chest size than weight? 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. Critical r: +0.2680855 P-value (two tailed): 0.000 O B. There is one critical value at r= s there sufficient evidence to support the claim that there is a linear correlation between the weights of bears and their chest sizes? Choose the correct answer below and, if necessary, fill in the answer box within your choice. "Round to three decimal places as needed.) O A. Yes, because the absolute value of the test statistic exceeds the critical value. O B. No, because the absolute value of the test statistic exceeds the critical value. O C. No, because the test statistic falls between the critical values. O D. Yes, because the test statistic falls between the critical values. O E. The answer cannot be determined from the given information.

Is there sufficient evidence to support the claim that there is a linear correlation between the weights of bears and their chest sizes? When measuring an anesthetized bear, is it easier to measure chest size than weight? 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. Correlation Results Correlation coeff, r: 0.969937 Critical r: + 0.2680855 P-value (two tailed): 0.000 B. There is one critical value at r= Is there sufficient evidence to support the claim that there is a linear correlation between the weights of bears and their chest sizes? Choose the correct answer below and, if necessary, fill in the answer box within your choice. (Round to three decimal places as needed.) A. Yes, because the absolute value of the test statistic exceeds the critical value. B. No, because the absolute value of the test statistic exceeds the critical value. O C. No, because the test statistic falls between the critical values. D. Yes, because the test statistic falls between the critical values. E. The answer cannot be determined from the given information.
