The first error is the statistical error and the second error is the systematic error. This result has been published: The CDF Collaboration, F. Abe et al., Phys.Rev. D57, 5382 (1998).
From the analysis of partially reconstructed 
decays, there is a published result from the analysis of Run 1a data
(integrated luminosity of 
collected during 1992-1993):
The CDF Collaboration, F. Abe et al.,
Phys.Rev.Lett. 76 (1996) 4462.
The analysis of the full Run 1 data set (integrated luminosity of
collected during 1992-1996) yields:
This result has been published: The CDF Collaboration, F. Abe et al., Phys.Rev. D58, 092002 (1998).
The combination of the above two results using exclusive and partially reconstructed B decays yields
The error is the sum of statistical and systematic errors, where the correlated systematic errors are taken into account.
From the analysis of the full Run 1 data set (
),
the exclusive signal 
yields:
(signal =

From the analysis of the partially reconstructed decay mode
, with
using the full Run 1 data set (

decay modes,
(signal

This result has been published: The CDF Collaboration,
F. Abe et al.,
Phys.Rev. D59, 032004 (1999).
No combination of the lifetime from the exclusive mode and partially
reconstructed mode has been made. Using the average CDF 
lifetime
and the 
lifetime from semileptonic decays, we determined the
CDF average 
lifetime ratio to be
The error is the sum of statistical and systematic errors, where the correlated
systematic errors are taken into account.
