Population Distribution and SurvivorshipCemetery DataName __SaadMohammed______________________________ Per.__4__Most individuals do not reach the maximum life span of their species, and many dieprematurely. The ratio of age at death to the surviving portion of a population is afunction of the species and, for human populations, also of the historical period andits socio-economic conditions. A survivorship curve shows the probability that anindividual of a particular species, age, and gender will survive to a certain age.InPart 1of this lab, you will organize actuarial data to produce survivorship curves.survivorship curve is normally generated by plotting the logarithm of the fractionofindividuals surviving against the age of the individual. In this relatively smallstudy,logarithms will not need to be computed. It is possible and often useful tocomparethe survivorship of different species by stretching or shrinking the x-axisso thattwo or more curves end at the same point, the maximum lifespan for thespecies. Inthis lab you will graph and compare the two genders of the humanpopulation.Part 1: Producing a human survivorship curveYou will collect data on age of death from cemetery data available on the Internet.Each group will select a different cemetery to collect their data from. The cemeteryneeds to have at least approximately 300 headstones total to provide enough data,with about one half males and the other half females.1. Go to the website:2. Go to theNew Jersey Table of Contentsand select any cemetery from anycounty in the state that has enough information as described above.A
