A very large study showed that aspirin reduced the rate of first heart attacks by 44%. A pharmaceutical company thinks they have a drug that will be more effective than aspirin, and plans to do a randomized clinical trial to test the new drug. What is the null hypothesis the company will use

The null hypothesis the company would use is:

H0 = Drug A being more effective than Aspirin in the treatment of heart attack

Explanation:

In statistical analysis of the a hypothesis, it is the aim of the experimenter to show if there is any significant difference between the proposed objective and the desired results being sought for.

In the case of the pharmaceutical company, since they are trying to show that there is a significant improvement when thier drug is used (Drug A ) for treatment of heart attacks when compared with Aspirin drugs, they would adapt the null hypothesis stated above.

This shows that, both Drug A and Aspirin would be used in the treatment of two different individual and the results obtained compared together to determine which drug has significant effects in heart attack treatment.
