Statistics
In the one-sample case, you are comparing the statistic from a sample to a known population parameter to determine whether the sample is from the general population. In the two-sample case, you are comparing the statistics from two different samples to determine whether the samples are from the same or different populations. There are important differences between the one-sample case and the two-sample case. Suppose you decide to test whether the mean SAT score of students who took an intensive SAT preparation course is the same as that of students who didn't take an SAT preparation course. Will this consist of a one-sample or a two-sample hypothesis test? O Neither O One-sample OTwo-sample The two-sample case requires the assumption that there is independent random sampling. Suppose you decide to investigate whether participation in intensive SAT preparation courses affects SAT scores. You go to several rigorous college preparatory schools and question the first few students as they arrive. You ask whether they took an intensive SAT preparation course, and, for those who did, you ask for their SAT scores. You questioned a total of 136 students, 101 of whom took an intensive SAT preparation course and 35 of whom did not. Are both samples independent random samples? Not applicable O No O Yes Can you use the sample or samples you collected to conduct the hypothesis test you will use to investigate your research question? Yes O No O Not applicable
