Some statisticians believe that the method called extreme value theory (EVT) is a powerful analytical tool. The curves generated by traditional statistical methods to analyze empirical data on human longevity predict that some humans would live beyond 130 years. According to the curves EVT generates, however, the limit on human life spans is probably between 113 and 124 years. To date, no one has lived beyond the upper limits indicated by EVT analysis.
Which one of the following can be properly inferred from the statements above?
a. EVT is, in general, a more reliable method for projecting future trends based on past observations than are traditional statistical methods.
b. EVT fits the data about the highest observed human life spans more closely than do traditional statistical methods.
c. According to the findings derived through the use of EVT, it is physically impossible for any human being to live longer than 124 years.
d. Given the results generated by EVT, there is no point in conducting research aimed at greatly extending the upper limit on human life spans.
e. Traditional statistical methods of empirical data analysis should eventually be replaced by some version of EVT.
