Life expectancy for all the different countries in the world ranges from a low of only 52.2 years (in Sierra Leone) to a high of 84.7 years (in Hong Kong). Life expectancies are clustered at the high end, with about half of all the countries having a life expectancy between about 74 and the maximum of 84.7. A few countries, such as Sierra Leone, have a very low life expectancy. A. What is the shape of the distribution of life expectancies for all countries?
A) Symmetric. B) Skewed to the right. C) Skewed to the left. D) None of these. B. From the information given, estimate the median of the life expectancies. C. Will the mean be larger or smaller than the median?
