Question

The following data are the three-year rate of return (%) oil investments for 40 mutual funds during 2001-2004. Construct a stem plot of the data using repeated stems (see Example 1.7). At approximately what value is the distribution of the data centered? Calculate the five-number summary [n; MIN, f1 , MED, fu , MAX] and the fourth spread (fs). Does the distribution appear to be symmetric or skewed? If it is skewed, what is the direction of the skew? Find the outliers or extreme outliers in the data set, if there are any. Construct a modified box plot for the data. Based on the stem plot, how many modes do you see in the distribution of these data, and where are they located?

Explanation / Answer

I see one mode around 18: 1|11233 1|5567778888899 2|012233444 2|67799 3|0122 3|678 4| 4|6
