Answer 1

Answer:

Based on the given information:

• To test new chemical (Antriste) that doctors believe may help with depression
• Total number of patients = 300
• Number of groups = 3 with 100 patients each
• Double blind study
  • Group 1: Palcebo
  • Group 2: Antriste - new drug
  • Group 3: Prozac drug
• Level of depression was recorded via a questionnaire over a year

1) What question is being asked in the experiment above?

• The question being asked in the experiment is whether the newly discovered drug Antriste is effective in treating depression.

2) What hypothesis is being tested in the experiment described above?

• The hypothesis being tested is if the newly discovered drug Antriste is more efficacious in treating depression as compared to Prozac as assessed based on the questionnaire filled by subjects over the course of a year.

3) What is the prediction based on this hypothesis?

• If the newly discovered drug Antriste is efficacious in treating depression, then their will be a significant difference in the level of depression as determined based on the questionnaire filled by patients.

4a) Is the hypothesis you wrote above testable?

• Yes this hypothesis is testable since it can be proved or disproved based on the data collected during the drug testing. If the variables cannot be measured, the hypothesis cannot be proved or disproved. In this case it can be tested by research and experimentation.

4b) Is the hypothesis you wrote above falsifiable?

• Yes, the hypothesis is falsifiable since the statement can be refuted based on the scientific study and experiment.
