5. A two-tailed hypothesis test for a repeated-measures design A graduate student is interested in whether jounaling can affect grief and healing. For her study, she selects a random sample of 64 adults who have been widowed within the past 10 to 14 months. The subjects complete a battery of psychological questionnaires before and after spending two months journaling about their emotions. Before the two months of journaling, the mean score on the impact of event scale-avoidance subscale, which measures...

INFORMATION ABOUT IMAGE G FOR QUESTIONS 12-15:
GABAB receptors (GABABRs) are
G-protein-coupled receptors that can be found on both pre- and
postsynaptic neurons. When they are activated by GABA, they can
have a range of effects. For the synapse you are studying in the
following questions, the effects of GABABRs are
indicated in IMAGE G.
You are doing a series of experiments in which you are recording
from the pre- and postsynaptic cell at a synapse. The experiments

DATA 4.1 Does Light at Night Affect Weight Gain? Numerous studies have shown that exposure to light at night is harmful to human health. A recent study? examines the effect of light at night on body mass gain in mice. Eighteen mice were randomly assigned to one of two groups: the Dark group had a normal light/dark cycle with darkness at night and the Light group had a dim light on at night, equivalent to having a television set on...
