JIZ NAVIGATION Question 1 Not yet answered Points out of 1.00 P Flag question The production of wine is a multibillion-dollar worldwide industry. In an attempt to develop a model of wine quality as judged by wine experts, data was collected from red wine variants of a 9 10 certain type of wine. A simple linear regression model yields bo = 6.2 and b1 = 0.1. Interpret the meaning of the slope, b1. Which of the following is a correct interpretation of b17 Select one: ish attempt ... a. The slope, b1, implies that for each 0.1% decrease in alcohol content, the wine should have an increase in its rating by 1. he left 2:59:34 Ob. The slope, b1, implies that for each increase of alcohol percentage of 1.0, the wine quality rating is expected to increase by the value of b1, Oc. The slope, b1, implies that the alcohol content is equal to the value of b1, in percentage. Question 2 Not yet answered Points out of 1.00 P Flag question For the same wine quality regression model as in question 1, with b0 = 6.2, b1 = 0.1, if the value of the alcohol content is 12.9, which of the following is the correct prediction value of the quality of wine? Select one: Oa. 7.29 Ob. 7.39 Oc. 749 Question 3 Not yet answered Points out of 1.00 P Flag question If the value of the independent variable in a simple linear regression model ranges from 5 to 37, which of the following is an incorrect value for prediction of the dependent variable?
