Question

An experiment was conducted to see the effectiveness of two
antidotes to three different doses of a toxin. The antidote was
given to a different sample of participants five minutes after the
toxin. Twenty-five minutes later the response was measured as the
concentration in the blood. What can the researchers conclude with
α = 0.01?

Compute the appropriate test statistic(s) to make a decision
about *H*_{0}.

Hospital administrators at a local hospital are interested in
quality of care. As such, they ask a random sample of patients that
have used the hospital's health care services to fill out a
questionnaire. The questionnaire has questions about the patient's
worry (negative, positive), the hospital staff's communication
skills (low, medium, high), and satisfaction with medical care. The
administrators are interested in how patient's worry and their
assessment of the hospital staff's communication impact their
satisfaction with medical care. The...

In a study of memory process, rats were first presented with a
fear-inducing stimulus on a learning task as soon as they stepped
across a line in a test chamber. Afterwards, the rats were divided
and given electrical stimulation either 50 or 150 milliseconds
after crossing the line. In addition, the rats differed in terms of
the area in which the stimulation electrodes were implanted in
their brains (Neutral Area, Area A, or Area B). Researchers were
interested in the...
