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 17 wines, a model was created using the percentages of alcohol to predict wine quality. From the results of that regression, b = 0.2067 and S, = 0.1976. 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, Bı. a. Determine the hypotheses for the test. Choose the correct answer below. O C. Ho: Boso H: Bo > 0 O A. Ho: B2 = 0 H: 8,0 OD.

Identify the p-value of the test statistic. p-value = 0 (Round to three decimal places as needed.) Reach 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 iss,s- (Round to three decimal places as needed.)
