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, b, = 0.3103 and Sb. = 0.1081, 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, B, ... a. Determine the hypotheses for the test. Choose the correct answer below. O A. Ho: B, 50 H, B,> 0 OD.

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 sb,50 (Round to three decimal places as needed.)
