Question

I need correlation coefficient ,test statistic , p value & conclusion pls help I need in an hour

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 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 coeff, r: 0.967386 Critical r: +0.2680855 P-value (two tailed): 0.000 Determine the null and alternative hypotheses. Ho: P Hq:p # 0 (Type integers or decimals. Do not round.) Identify the correlation coefficient, r. (Round to three decimal places as needed.)
