 It turns out that the standard deviation of the bootstrapped means from @fig-carsbsmean is \$2,891.87 (a value which is an excellent approximation for the standard error of sample means if we were to take repeated samples from the population).
 (Note: in R the calculation was done using the function `sd()`.)
