Life Expectancy Infant Mortality Rate and Per Capita Gross N
     Life Expectancy, Infant Mortality Rate, and Per Capita Gross National Income by Selected  Using Table 1, calculate the mean life expectancy for the nine countries. 7 points  From Table 1, what is the median infant mortality rate for the nine countries? 7 points 
  
  Solution
1. Mean Life expectancy for the nine countries = Total life expectancy / Number of countries
= 78.4+73.8+79.4+76.3+75.6+73+32.4+40.1+65.9/ 9
= 594.9/9 = 66.1 years
