Suppose you interview 10 randomly selected workers and ask how many miles they commute to work. You'll compute the sample mean commute distance. Now imagine repeating the survey many, many times, each time recording a different sample mean commute distance. In the long run, a histogram of these sample means represents

a. the bias, if any, that is present in the sampling method.

b. the sampling distribution of the sample mean

c. the true population average commute distance

d. a simple random sample.
