The bootstrap distribution is centered around the sample ¯ statistic, x = 98 . 26, with of SE = 0 .109, a 95% confidence interval is Statistic ± 2 · SE = 98.26 ± 2 · 0.109 = ( 98.042, 98.478 ) A 95% confidence interval can also be found as the middle 95% of bootstrap statistics, shown in the figure to be (98.044, 98.476). We are 95% confident that mean body temperature is between 98.04 ◦ F and 98.48 ◦ F.
