The following data on distilled alcohol content (%) for a sample of 35 port wines was extracted from the article “A Method for the Estimation of Alcohol in Fortified Wines Using Hydrometer Baumé and Refractometer Brix” (?Amer. J. Enol. Vitic.,? 006: 486–490). Each value is an average of two duplicate measurements. Use methods from this chapter, including a boxplot that shows outliers, to describe and summarize the data.

Solution : Step 1 The given data is on distilled alcohol content (%) for a sample of 35 port wines.,to find the alcohol content in the wines. It is also given that each value is an average of two duplicate measurements. We have to make a boxplot based on the given data and we have to summarize and interpret the data. Step2 : By arranging the data into ascending order we will get 15.3 16.2 16.35 17.15 17.48 17.73 17.75 17.85 18 18.68 18.82 18.85 19.03 19.07 19.08 19.17 19.2 19.2 19.33 19.37 19.45 19.48 19.5 19.58 19.6 19.62 19.9 19.97 20 20.05 21.22 22.25 22.75 23.25 23.78 From the arrangement it is clear that the median median= 18th observation = 19.20 Smallest value=...
