B) computes a standardized score for that mean.
C) compares that to a distribution of mean by calculating a z statistic.
D) standardizes that using information about the center and spread of the population of scores.

When one is unable to access the entire population, they typically calculate the mean of a sample and then compare it to the distribution of mean. This is done by calculating a z statistic, which allows for comparison of the sample mean to the population mean. Therefore, the best choice is C, which states that one compares the sample mean to a distribution of means by calculating a z statistic.
