1-Answer the following questions using the measures of central tendency and variability:
a.Summarize the cost effectiveness (COST) and total assets (SIZE) of all the firms.
b.Interpret the existence or lack of a symmetry in the distributions of COST and SIZE of all the companies.
c.Compare the cost effectiveness and size of the companies between the three categories of industry risk.
d.Compare the cost effectiveness and size of the companies between the three categories of importance they place on the use of analytics in managing risks.
2-Having described in general the distribution of the SIZE of all the companies using measures of central tendency and variability in Question 1, now explain more specifically the symmetry and skewness of the distribution.
a.What can you conclude about the distribution (including skewness, outliers) of the size of all companies? Justify your answer by a boxplot, and a stem-and-leaf display.
b.How many outliers (on either end) are there in part a?
c.Compare the distributions of size of companies in the 3 categories of industry risk using box plots. What conclusions can you draw from your observations of the box plots?
