1a) A researcher conducts an independent-measures study to examine 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, low serotonin group, 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. See the data below. Is there...

Democrats and Republicans were surveyed on their support of gun control legislation using a standardized measure (high scores representing greater support of gun control). Using the data provided, test the difference between the means (assume a two-tailed t-test) and answer the questions below: Democrats                                                       Republicans N = 50                                                              N = 40 Mean = 6.0                                                                  Mean = 4.9 Standard Deviation = 1.2                                 Standard Deviation = 1.4 8.

A study comparing children’s reading age (in months) was developed using identical twin toddlers. One set of 6 twins played for 2 hours each day with educational toys (experimental group), the corresponding set of 6 twins played for 2 hours each day with non-educational toys (control group). The mean difference in reading age between the experimental group and control group of 6 sets of twins was -2.33 months and the standard deviation of the sample difference was 2.16 months. Set...
