A researcher randomly assigns 118 critically ill patients to receive a drug and 234 to receive a placebo. Among those assigned to the Drug Arm of the study 47 died and among those assigned to the Placebo Arm 51 died.
Determine the conditional odds of randomly selecting a study participant who died given that he or she was randomly assigned to the Drug Arm of the study. Round your final answer to the nearest thousandth.

Suppose that we have developed a new drug for critically ill
patients. In the control group of 36 patients, given a placebo, the
average time to release from the ICU was 12.8 days. In the group of
50 patients that we gave our experimental drug, the average time to
release from the ICU was 12.1 days. Assuming both populations had
the same standard deviation of 3.6 days and the same proportion of
recoveries, would you say there is evidence of...

A researcher randomly assigns five individuals to receive a new
experimental procedure, measuring number of decision-making errors
before and after the procedure. Baseline scores were 7, 6, 9, 7,
and 6. Scores after the experimental treatment were. 5, 2, 4, 3,
and 6. Conduct a two-tailed hypothesis test with α = .05, being
sure to specify the null and alternative hypotheses.

A researcher is investigating the effects of emotion and gender
on cooperation. He randomly assigns participants to one of three
conditions: control, guilt, happiness
After inducing one of the three emotions, the researcher measures
each participant's level of cooperation in a game, on a scale from
1 to 10.
Men:
Control: 5 4 7 4 3 5 5 6
Guilt: 6 9 7 8 6 7 7 8
Happiness: 8 7 8 9 9 6 8 9

Questions 8 – 13. In an experiment examining
humor and memory, a researcher randomly assigns participants to one
of two groups. Half of the participants saw sentences that were
humorous and the other half of participants saw sentences there
were non-humorous. The researcher measures the number of sentences
recalled and hypothesizes that the humorous group will remember
more sentences than the non-humorous group.

A researcher tests a new drug on a sample of known schizophrenic
patients, hypothesizing it will reduce their symptoms. After the
drug trial their symptom scores are assessed (higher scores = more
disordered, lower scores = more healthy). This score is converted
into a z score of -2.11. The researcher used an alpha of .05.
a. What is the p-value for this study?
b. What do you conclude from this test?
c. What does the p value mean or what...
