In an attempt to develop a model of wine quality as judged by wine experts, data on alcohol content and wine quality was collected from variants of a particular wine. From a sample of 19 wines, a model was created using the percentages of alcohol to predict wine quality. From the results of that regression, b4 = 0.5667 and Spy = 0.1707. a. At the 0.05 level of significance, is there evidence of a linear relationship between the percentage of alcohol and wine quality? b. Construct a 95% confidence interval estimate of the population slope, B1. a. Determine the hypotheses for the test. Choose the correct answer below. O A. Ho: Bo = 0 H: Bo70 OD. Ho: B. =0 H: Bo>0 O B. Ho: B2 = 0 H: 8,70 O E. Ho:B120 H: B, < 0 OC. Ho: B230 H: B,>0 OF. Ho: Bo=0 H1: B. < 0 Compute the test statistic. ESTAT = (Round to two decimal places as needed.) Identify the p-value of the test statistic. p-value = (Round to three decimal places as needed.) Reach a decision. Ho. There is evidence to conclude that there is a linear relationship between the percentage of alcohol and wine quality. b. The 95% confidence interval is sp,$. (Round to three decimal places as needed.)
