How do I calculate the 95% confidence interval it's asking for in the photo and Construct a?95% prediction interval estimate for the quality rating for an individual wine that has 9% alcohol and 0.09
Score: 0.55 of 1 pt 3 of 3 (3 complete) HW Score: 84.85%, 2.55 of 3 p x 13.1.5-T Question Help 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. A sample of 20 wines is provided in the accompanying table. Develop a multiple linear regression model to predict wine quality, measured on a scale from 0 (very bad) to 10 (excellent) based on alcoho ts a through g below. i Wine Quality X Click the icon to view the table. O B. For every increase of one unit of alcohol content, the estimated number of chlorides and mean wine quality decreases by the values of b, and b2 units, r C. For a given number of chlorides, each increase of one percentage of alcohol content is estimated to result in a mean increase of wine quality of b, units. chlorides is estimated to result in the mean increase in wine quality of b2 units. Quality Alcohol Content (%) Chlorides O D. The slopes, b, and b2, cannot be interpreted individually. 1.3 0.069 O 7.4 0.069 8.6 0.074 c. Explain why the regression coefficient, bo, has no practical meaning in the context of this problem. WWNC 7.9 0.073 8.3 0.067 A. The interpretation of bo has no practical meaning here because it would correspond to the estimated mean alcohol content when a wine has a 0 quality a 3 9.1 0.077 8.3 0.076 B. The interpretation of bo has no practical meaning here because it would correspond to the estimated mean alcohol content and mean chlorides when the 9.1 0.076 10.2 0.077 C. The interpretation of bo has no practical meaning here because it would correspond to the estimated mean quality when a wine has a 0% alcohol content 10.3 0.081 10.5 0.077 D. The interpretation of bo has no practical meaning here because it would correspond to the estimated mean chlorides when a wine has a 0% alcohol cont 10.8 0.083 10.8 0.085 d. Predict the mean quality rating for wines that have 9% alcohol content and chlorides of 0.09. 11.8 0.085 11.7 0.098 The wine quality prediction for a wine that has 9% alcohol and 0.09 chlorides is 3.55 . 11.3 0.097 11.9 0.097 (Round to two decimal places as needed.) 12.5 0.115 e. Construct a 95% confidence interval estimate for the mean quality rating for wines that have 9% alcohol and 0.09 chlorides. 12.8 0. 151 12.5 0. 159 The 95% confidence interval estimate of the mean quality rating for wines that have 9% alcohol and 0.09 chlorides is to .
