please!
According to the historical data, the life expectancy in Belgium is less than the life expectancy in the United States. A new study has been made to see whether this has changed. Records of 220 individuals from Belgium who died recently are selected at random. The 220 individuals lived a mean of 78.3 years with a standard deviation of 7.1 years. Records of 225 individuals from the United States who died recently are selected at...
