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 a = .05, being sure to specify the null and alternative hypotheses

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.

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

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 randomly assigns 33 subjects to one of three
groups. Group 1 receives technical dietary information
interactively from an on-line website. Group 2 receives the same
information from a nurse practitioner, while Group 3 receives the
information from a video made by the same nurse practitioner.
The researcher looked at three different ratings of the
presentation: difficulty, usefulness, and importance to determine
if there is a difference in the modes of presentation. In
particular, the researcher is interested in...

After measuring two individuals, a researcher can say that the
score for one individual is larger that the score for the other,
but it impossible to say how much larger. Would this scale fo
measurement be ordinal?

An educator randomly assigns students to a program in which some
will use new reading activities and others traditional teaching
methods. At the end, both groups take a reading comprehension
exam. Their scores are shown in the back-to-back stem-and-leaf
display. Do these results suggest that the new activities are
better? Test an appropriate hypothesis and state your conclusion.
(Assume a significance level of alpha=0.05.)
