In an attempt to develop a model of wine quality as judged by wine experts, data on alcohol content and wine quailty 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,=0.3074 and So, -0.1174. 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, a. Determine the hypotheses for the test. Choose the correct answer bolow OA. Hoilo He: 0 OD. Ho: B, 50 H> 0 OB. Ho 3,20 H: Boco O E. Ho Bo=0 H: Poto OCH 1,20 HB0 OF. Holoso H: >0
Compute the test statistic (Round to two decimal places as needed.) Identify the p-value of the test statistio. p-value = (Round to three decimal places as needed.) Reach a decision, H, 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, (Round to three decimal places as needed.)
