12.0.5f1.5 poinls | Previous Answers One of the methods forensic investigators use For estimating the age at death of a human, or the age of a living individual [for example For legal reasons or to verih:r identith is based on measurement of the biochemical changes in amino acids within the teeth or bones. As bones and teeth age the Iao E of two amino acids, denoted simply as R L and L, increases. The biochemical changes that occur over time in these amino acids follow an exponential law. The 1 + % l l _I age t. in veers, can be estimated from E using the equation t = bu + b1*LN( I. j, where LN denotes the natural logarithm [logarithm base e}. This Excel le has data on the ratio E from the teeth of human subjects of known age. L g Question 1. Use the data to nd the least squares slope b1 and interoept bu in the equation t = on + b1*LN(l + L ) a: slope b. X intercept bu
