Problem 34BB

Censored Data Data set 12 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 33 years, 21 years, 17 years, 9 years, and 1 year so far. We might use the values of 33 + , 21 + , 17+, 9 + , and 1 + , where the plus signs indicate that the actual value is equal to or greater than the current value. (These values were said to be censored at the time that this list was compiled.) If you use the values in Data Set 12 and ignore the presidents who are still alive, what is the mean? If you use the values given in Data Set 12 along with the additional values of 33 + , 21 + , 17+, 9 + , and 1 + , what do we know about the mean? Do the two results differ by much?

The "Mean" is computed by adding all of the numbers in the data together and dividing by the number elements contained in the data set.

Mean (without) = = 15.0303
