A researcher conducts a study measuring differences in brain activity among rats placed on either a continuous or intermittent reward schedule.Assuming that the population variance in unknown,what type of t test is appropriate for this study?
A)one-sample t test
B)two-independent sample t test
C)not enough information

Question

Quizplus · Accepted Answer

This is the appropriate choice because the study involves comparing two independent groups (rats on continuous vs intermittent reward schedule) and the population variance is unknown. A two-independent sample t test is used to determine if the means of the two groups are statistically different from each other.
