Question:

The table above shows the degree of satisfaction with the economy of the country in various geographical regions as indicated by a “satisfaction index”. The index is measured on a scale of 0 to 100 with higher numbers indicating a higher degree of satisfaction.

a. For each of the three data sets, indicate what the corresponding data type is and explain your choices.

b. The average satisfaction index is reported to be 79.1. The accuracy of this average is questioned because “if most of the regions have a score above 80, why is the average in the 70s”? How would you respond to this enquiry?
