Conceptual Set 1. The same researcher wants to then compare the final (time 2) levels of anger in this experimental group to a control group that just had the water balloons thrown at them. He compares the group from the previous questions to a group who did not do pushups. Which t-test should he use?

QUESTION 55-Conceptual Set 1. Why should the researcher from question 54 use that test?

A. Because single sample t-tests compare a sample mean to a population mean, which is what the researcher is attempting to do
B. Because single sample t-tests compare scores before and after an event, which is what the researcher isattempting to do
C. Because single sample t-tests compare two completely different groups in a sample, which is what the researcher is attempting to do
D. Because paired samples t-tests compare a sample mean to a population mean, which is what the researcher is attempting to do
E. Because paired samples t-tests compare scores before and after an event, which is what the researcher is attempting to do
F. Because paired samples t-tests compare two completely different groups in a sample, which is what the researcher is attempting to do
G. Because independent sample t-tests compare a sample mean to a population mean, which is what the researcher is attempting to do
H. Because independent sample t-tests compare scores before and after an event, which is what the researcher is attempting to do
I. Because independent sample t-tests compare two completely different groups in a sample, which is what the researcher is attempting to doA
