No, that is not correct. The bootstrap is only intended
as a way to calculate standard errors and confidence
intervals. It does not and should not change the point
estimates. The following book is a very readable and
instructive introduction to the bootstrap:
Bradley Efron and Robert J. Tibshirani (1998) An
Introduction to the Bootstrap. Monographs on Statistics
and Applied Probability, nr 57. Boca Raton: Chapman &
Hall/CRC.
Hope this helps,
