I want to estimate the population mean using 100 samples. The reasonable estimate of the population mean is the sample mean. I am wondering, why bootstrap can give more accurate result than the sample mean? I mean, when I am doing resampling, will I get more information about the sample in order to infer the population parameter?

    $\begingroup$ The bootstrap mean equals the sample mean, so it will never give a more accurate result for this particular estimator. The bootstrap might give you useful information about the sampling distribution of the mean. $\endgroup$
