Quizplus · Accepted Answer

The appropriate test statistic for this data is the one-sample t test because the researcher is comparing the pulse rate of a sample of college runners to the population mean of the Olympic runners, and she does not know the population standard deviation. Therefore, the t distribution should be used.
