There are 8146 male employees studied from 1946 to 1981. Comparisons were made for causes of death between mortality rates in these workers and U.S. white male mortality rates from 1950 to 1978. There were 17 deaths from cirrhosis of those hired before 1946 and worked for 10 years or more, compared to 6.3 was expected based on U.S. mortality rates. Perform a significance test to see if there is a relation between mortality and duration of employment in the group hired AFTER 1945 and report a p-value.
