Question

- A pharmaceutical company performs an experiment to test a new
drug against Coronavirus (SARS2-COV). Their scientists
predict that this drug will reduce the length of hospital stay for
patients, compared to the current standard
treatment. One group of patients (Group A) is given the
new drug. One group of patients (Group B) is given the
current standard treatment. The average length of
hospital stays were as follows: Group A: 6
days. Group B: 11 days.
- What is the hypothesis?
- What is the control?
- What is the experimental (or independent) variable?
- What is the responding (or dependent) variable?
- What should their conclusion be?

Answer #1

1. What is hypothesis-- drug will reduce the length of hospital stay for patients, compared to the current standard treatment.

2. What is the control

Group B which is given standard treatment is the control

3.What is the experimental (or independent) variable

The type of new drug given to participant is the independent variable

4.What is the responding (or dependent) variable

The average length of hospital stays is the dependent variable

5. What should their conclusion be

Ho - the new drug will reduce the length of hospital stay for the patients

H1 - the new drug will not reduce the length of hospital stay for the patients

But according to the test conducted we can conclude that the hypothesis was true and the new drug will reduce the length of hospital stay for patients compared to the control drug.

A manufacturer has produced a new drug for depression. The
pharmaceutical company performed a study in which 25 depressed
subjects took the new medication and 25 depressed subjects took a
placebo pill. Neither the subjects nor the examiners administering
the questionnaire knew who was in the drug group and who was in the
placebo group.
After 2 months, the subjects who took the drug had significantly
improved scores on a standardized depression symptom questionnaire.

A new drug to treat high cholesterol is being tested by
pharmaceutical company. The cholesterol levels for 18 patients were
recorded before administering the drug and after. The average
difference in cholesterol levels (after - before) was 4.19 mg/dL
with a standard deviation of 8.055 mg/dL. Using this information,
the calculated 90% confidence paired-t interval is (0.887, 7.493).
Which of the following is the best interpretation of this
interval?
Question 8 options:
1)

people are randomly assigned to the experimental group, and they
receive the new drug for six weeks. The other 25 people are
randomly assigned to the control group, and they receive the

A pharmaceutical company is testing a new drug to increase
memorization ability. It takes a sample of individuals and splits
them randomly into two groups. One group is administered the drug,
and the other is given a placebo. After the drug regimen is
completed, all members of the study are given a test for
memorization ability with higher scores representing a better
ability to memorize. You are presented a 90% confidence interval
for the difference in population mean scores (with...

A pharmaceutical company is testing a new drug to increase

them randomly into two groups: group 1 takes the drug, group 2
takes a placebo. After the drug regimen is completed, all members
of the study are given a test for memorization ability with higher
scores representing a better ability to memorize. Those 30
participants on the drug had an average test score of 32.74 (SD =

A physician at the veterans’ hospital would like to try a new
MAOI (monoamine-oxidase inhibitor) drug for his veteran patients

patients with PTSD to record each incident of a nightmare for 1
month before treatment. Participants were then given the MAOI
medication for 6 weeks, and then they were again asked to record
each occurrence of a...
