eth Bus (385:02) Exam #2 04/05/23 Question 2 of 9 > The information shown below is available for two samples selected from independent populations. What is the value of T, if you are testing the null hypothesis Ho: M = M? Sample 1: n = 7 Sample 2: n = 9 Assigned ranks: 13 928 16 5 11 Assigned ranks: 12 3 1 14 10 15 7 4 6 This test: 29 point(s) possible This question: 1 point(s) possible The value of the test statistic T, is 3 Submit test t Meth Bus (385:02) Exam #2 04/05/23 Question 1 of 9 > This test: 29 point(s) possible This question: 4 point(s) possible Submit test 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 12 wines, a model was created using the percentages of alcohol to predict wine quality. For those data, SSR=21,859 and SST = 33,962. Use this information to complete parts (a) through (c) below. a. Determine the coefficient of determination, r, and interpret its meaning. (Round to three decimal places as needed.) Interpret the meaning of r. It means that % of the variation in (Round to one decimal place as needed.) b. Determine the standard error of the estimate. Syx = (Round to four decimal places as needed.) can be explained by the variation in c. How useful do you think this regression model is for predicting wine quality? A. It is not very useful for predicting wine quality because the coefficient of determination is close to 1. B. It is very useful for predicting wine quality because the coefficient of determination is close to 0. C. It is not very useful for predicting wine quality because the coefficient of determination is close to 0. D.
