A medical data repository contains records of 100,000 deceased persons. An autopsy performed on those persons has revealed 48,350 cases of a structural heart defect (SHD). Histogram of the life-time of persons affected with SHD shows an exponential distribution with average T1=47.1 years. Life-time of the remaining persons reveals an exponential distribution with average T0=72.8 years. If a person dies at an age of 57, would you say that this person had SHD? Apply the maximum a-posteriori probability (MAP) criterion to answer the question. Note: Exponential distribution is defined by fX(x)= 1 mX e−x/mX for x≥0, where mX=E{X}. Numbers are rounded.单项选择题
