It is generally claimed that life expectancy tended to increase during the 19th and 20th centuries because of improvements in public health systems (eg sewage and sanitation) and medical advances. In a graveyard in Scotland, you find the year of death and age of death of 13 males from the Dunachie family. The data are given below. Is there any evidence that life expectancy was increasing for that family? Plot a scatterplot and choose an appropriate correlation to calculate for this data.
