Question
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, b1=0.4386 and Sb1=0.1141.
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, β1.
