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 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 0 05 Identify the critical value s Round to three decimal places as needed A There are two critical values at r 0 268 OB There is one critical value at r falls between the critical values Correlation Results Correlation coeff r 0 950958 Critical r 0 2680855 P value two tailed 0 000 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 0 951 exceeds the critical value exceeds the critical value B No because the absolute value of the test statistic OC No because the test statistic OD Yes because the test statistic falls between the critical values OE The answer cannot be determined from the given information 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 OA Yes it is easier to measure a chest size than a weight because measuring weight would require lifting the bear onto the scale The chest size could not be used to predict weight because there is not a linear correlation between the two OB No it is easier to measure weight than chest size because the chest is not a flat surface OC Yes it is easier to measure a chest size than a weight because measuring weight would require lifting the bear onto the scale The chest size could be used to predict weight because there is a linear correlation between the two bort size than a weight because measuring weight would require lifting the bear onto the scale The chest size could not be used to predict weight because there is
