The production of wine is amultibillion-dollar worldwide industry. In an attempt to develop a model of wine quality as judged by wineexperts, data was collected from red wine variants of a certain type of wine. A sample of 12 wines is given. Develop a simple linear regression model to predict winequality, measured on a scale from 0(very bad) to 10(excellent), based on alcohol content(%). Complete parts(a) through(d) below.

A hospital was concerned about reducing its wait time. A targeted wait time goal of 25 minutes was set. After implementing an improvement framework and process, a sample of 349 patients showed the mean wait time was 23.07 minutes, with a standard deviation of 16.93 minutes. Complete parts (a) and (b) below. . . . . a. If you test the null hypothesis at the 0.10 level of significance, is there evidence that the population mean wait time is less than 25 minutes? State the null and alternative hypotheses. O A. Ho: H 2 25 O B. Ho: H > 25 O C. Ho: H 25 O D. Ho: H # 25 O E. Ho: H 2 25 OF. HO: H
