The abridged life table data in the table below refers to the female population of England and Wales in 1980-82. They are based on an assumed 100,000 births and have been abridged from a full life table which used information by single years of age. Using these data, calculate the following: a) The probability that a woman aged exactly 20 years will survive until her 40th birthday b) 1QO c) The expectation of life at birth d) The expectation of life at age 1 e) The probability that a girl who survives until her rst birthday will die between her 10th and 20th birthdays f) The expected age at death of those who die between their 20th and 30th birthdays 9) The expected age at death of those who die when they are aged under 1 yean h) What do the results of (f) and (9) tell you about the validity of assuming that deaths are evenly distributed across age groups? Age (x) Survivors to age x, Ix Person-years lived above exact age x, Tx
