Question Help Fifty-four wild bears were anesthetized, and then their weights and chest sizes were measured and listed in a data set Results Commation Results are shown in the accompanying display Is there sufficient evidence to support the claim that there is a near correlation between Correlation coeff0 957692 the weights of bears and their chest sizes? When measuring an anesthetized bear, is it easier to measure chest size than weight? 005 Critical: If so, does it appear that a measured chest size can be used to predict the weight? Use a significance level of 02680855 P-value (two tailed): 0.000 Determine the null and alternative hypotheses HOPE HPD (Type integers or decimals Do not round) Identify the correlation coefficient, (Round to three decimal places as needed) Identify the critical values) (Round to three decimal places as needed) O A. There are two critical values at O B. There is one critical value atra 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.) Click to select your answer(s). ORE 9

Answer 1

r = 77 x = 492 s=29 Ho : P = 0 Hais # 0 8= 10.958 Critical values. (A. There are two critical values at r= I 10.2681 + #sco Yes, because the absolute value of the teststazistic is exceeds the critical value # A) vet it is easier to measure a chest size than a weight becuse measuring wesant would require lifting the bear anto me scale .The chest size could be used to predict weight because there is a linear coroln bet the two
