It would be interesting to know whether our learning groups differ on the dependent variable by comparison to population averages.
- It would be interesting to know whether our learning groups differ on the dependent variable by comparison to population averages. We happen to know that the population average of lever presses (dependent variable) for mice that have been positively reinforced is equal to 62 (s.d.), and for non-positively reinforced mice (i.e., control) the population mean is 55 (s.d.). Use a statistical test to compare our sample means for each learning group to the population means.
- we know the population variance
- direction is not important
- independent samples
I don't know which statistical test to use and how to start it. Is it a z-test or a t-test and why?
