Neuroscience researchers examined the impact of environment on rat development. Rats were randomly assigned to be raised in one of the four following test conditions: Impoverished (wire mesh cage - housed alone), standard (cage with other rats), enriched (cage with other rats and toys), super enriched (cage with rats and toys changes on a periodic basis). After two months, the rats were tested on a variety of learning measures (including the number of trials to learn a maze to a three perfect trial criteria), and several neurological measure (overall cortical weight, degree of dendritic branching, etc.). The data for the maze task is below. Compute the appropriate test for the data provided below.

A researcher is interested in the effects of cocaine on learning. A group of rats is randomly assigned to receive either cocaine or a non-harmful saline solution. The rats are taught how to run a maze. The cocaine rats need to be reared away from the control group rats, so they are handled and taught by one experimenter, and the control group rats are handled and taught by another experimenter. The results showed that the control group rats learned how to run the maze more quickly than the cocaine rats.

It is claimed that a vitamin supplement helps mice learn to run a maze more quickly and, in fact, to beat a non-treated mouse 70% of the time (whereas without the supplement, it would only win half of the time). To test this claim, you divide a group of 20 mice randomly into ten pairs, giving one of each pair the vitamin supplement. You run each pair through the maze and find that seven out of ten of the mice treated with the vitamin supplement beat the untreated mice.
a) What is the probability of obtaining this result if the claim is true?
b) What is the probability of obtaining this result if the claim is false (i.e., the supplement has no effect)?
c) Suppose before you ran this experiment, you thought it was equally likely that the claim was true or false. After running the experiment, what is your belief? What is the updated probability?

- Researchers conduct a study to test a potential side effect of a new allergy medication. A random sample of 160 subjects with allergies was selected for the study. The new "improved" Brand I medication was randomly assigned to 80 subjects, and the current Brand C medication was randomly assigned to the other 80 subjects. 14 of the 80 patients with Brand I reported drowsiness, and 22 of the 80 patients with Brand C reported drowsiness.

The researchers recruited 256 women living in the Midwest who were undergoing treatment for breast for four weeks. At the beginning of the study, all 256 patients were interviewed by trained data collectors via telephone. Data collectors recorded the age, race, ethnicity, level of education, employment income, and their relationship to their caregiver. They also recorded responses to questions evaluating their depressive symptoms and the severity of 13 medical symptoms such as pain, fatigue, nausea, dry mouth, etc. Symptoms were rated as mild, moderate, or severe.

- Exercise 4 Twelve people completed a difficult hand-eye coordination task twice: once in a quiet room, and once in the same room while loud rock-and-roll music was being played. The order in which subjects experienced these conditions was counterbalanced: half performed in the quiet environment first, half performed in the loud environment first. The researcher measured the number of errors committed by the participant while performing. Thus, the lower the score, the better the performance. Here are the results: Participant: 1 2 3 4 5 6 7 8 9 10 11 12 Quiet Environment: 14 21 24 16 18 20 15 20 17 16 19 12 Loud Environment: 21 22 21 19 18 25 17 18 21 24 21 15 Was there a significant difference in performance between the two treatment conditions (alpha = .05 Using these scores, carry out a t test for two related samples.

They conducted an experiment in which 20 basketball players with similar abilities were randomly assigned to two groups. The 10 players in group 1 received visualization training, and the 10 players in group 2 did not. Each player stood 22 feet from the basket at the same location on the basketball court. Each player was then instructed to attempt to make the basket until two consecutive baskets were made. The players who received visualization training were instructed to use visualization techniques before attempting to make the basket. The total number of attempts, including the last two attempts, were recorded for each player. The total number of attempts for each of the 20 players are summarized in the following boxplots.

Each subject participated in a two-phase experimental session. In the first phase, respiration was measured while the subject was awake and at rest. In the second phase, the subject was told to imagine that he was performing muscular work, and respiration was measured again. For subjects in the treatment group, hypnosis was induced between the first and second phases; thus, the suggestion to imagine muscular work was “hypnotic suggestion” for treatment subjects and “waking suggestion” for control subjects. The table below shows the measurements of total ventilation (liters of air per minute per square meter of body area) for all 16 subjects.

- An Instructor teaching three sections of Introductory Psychology, each section covering the same material. She has made up a different final exam for each section, but she suspects that one of the versions is more difficult than other two. She decides to conduct an experiment to evaluate the difficulty of the exams. During the review period, just before finals, she randomly selects five volunteers for each class. Class 1 volunteers are given version 1 of the exams, Class 2 volunteers get version 2, and Class 3 volunteers receive version 3. Of course, all volunteers are sworn not to reveal any of the exam questions and also, of course, all of the volunteers will receive different final exam from the one they took in the experiment.

In the study, thebirds were tested in a box with two chambers andwere free to move from one chamber to another. Inone chamber, two large eye-spots were painted onone wall. The other chamber had plain walls. Theresearcher recorded the amount of time each birdspent in the plain chamber during a 60-minute session.Suppose the study produced a mean of M = 34.5 minutes on the plain chamber with SS = 210 for a sample of n = 15 birds. (Note: If the eye spots have no effect,then the birds should spend an average of μ = 30minutes in each chamber.)a.

Some volunteers will be randomly assigned to drink caffeine-free cola; some to drink regular cola (with caffeine), and the others a mixture of the two (getting a half dose of caffeine). For each volunteer, a test score (the number of items recalled correctly) will be recorded.

In some instances, the toxicity of the cancer drug, that is, its effect on normal cells can be reduced by the simultaneous injection of a second drug. A study was conducted to determine whether a particular drug injection was beneficial in reducing the harmful effects of a chemotherapy treatment on the survival time for rats. Two randomly selected (independent) groups of rats, 12 rats in each group, were used for the experiment. Both groups, call them A and B, received the toxic drug in a dosage large enough to cause death, but group B also received the antitoxin that was intended to reduce the toxic effect of the chemotherapy on normal cells. The test was terminated at the end of 20 days, or 480 hours. The lengths of survival time for the two groups of rats, to the nearest 4 hours, are shown in the following table.
