Censored Data Data Set 15 “Presidents” in Appendix B lists the numbers of years that U.S. presidents lived after their first inauguration. As of this writing, five of the presidents are still alive and after their first inauguration they have lived 37 years, 25 years, 21 years, 13 years, and 5 years so far. We might use the values of 37+ , 25+, 21+ ,13+, and 5+, where the positive signs indicate that the actual value is equal to or greater than the current value. (These values are said to be censored at the current time that this list was compiled.) If you use the values in Data Set 15 and ignore the presidents who are still alive, what is the mean? If you use the values given in Data Set 15 along with the additional values of 37+, 25+, 21+, 13+,and5 + , what do we know about the mean? Do the two results differ by much?

Solution Summary: The author compares the mean number of years that U.S. presidents lived after their first inauguration with the additional values.
