A researcher conducts an independent-measures study examining how the brain chemical serotonin is related to aggression. One sample of rats serves as a control group and receives a placebo that does not affect normal levels of serotonin. A second sample of rats receives a drug that lowers brain levels of serotonin. Then the researcher tests the animals by recording the number of aggressive responses each of the rats display. The data are as follows. Control Low Serotonin n = 10 n = 15 M = 14 M = 19 SS = 180.5 SS = 130.0 A. Does the drug have a significant effect on aggression?Use an alpha level of .05, two tails.

In a study looking at undergraduate students’ perceptions of sense of community at their university, a researcher hypothesizes that the farther away students live from campus (in miles), the less they feel they are part of the university community. The researcher collected data for the following two variables – miles from campus and part of community (rating from 1-10 of how much they felt part of the university community). Proposed analysis (the kind of test) and why you chose the analysis: Scales of measurement (i.e., nominal, ordinal, interval or ratio) for variable(s) that will be used in the analysis: Null and alternative hypotheses (based on context of study) in symbols: Test assumptions and make a decision Inferential statistic(s) and p-value(s): Decision: conclusion Based on your decision, identify and explain the type of error you could be making with respect to the conclusions of the study
