A psychologist is interested in determining whether a new online pain management program improves (reduces) pain scores for its participants. A group of pain patients are randomly assigned to participate in either the online program or a control group. At the end of the study the researcher administered a widely used pain level scale ranging from 1-10. What is the null hypothesis for the study?

The available options are:

a. The percentage of treatment and control group participants with significant pain is the same in the population

b. The treatment group mean equals 1 in the population, and the control group mean is greater than 1 in the population

c. Both population means equal 1

d. The difference between the treatment and control group means is zero in the population

e. The difference between the sample means of the treatment and control group is zero

D. The difference between the treatment and control group means is zero in the population

Explanation:

Considering the fact a Null Hypothesis is a form of conventional statistical theory that proposes that there is zero or no statistical relationship and significance in a group of assigned single observed variables, between two groups of experimental data and assessed events.

In this case, the NULL HYPOTHESIS is the zero difference between the treatment or online group and the control group means in the population

the anti federalists was a movement that was opposed to the creation of a us federal government. although they were not as organized as the federalists, they also had a large group of leaders, especially in state politics.

the statement "now, in a large extended country, it is impossible to have a representation, possessing the sentiments, and of integrity, to declare the minds of the people” represents the concerns of the anti federalists.

they strongly believed that the federalists were representing the interests of aristocratic elements of society at the expense of the majority of ordinary people, who lived in a rural society.

their fear for the creation of a strong federal government and the president’s power of veto in their opinion would create a tyrannical rule that would dominate the people. they defended the importance of restraining the government’s power towards people at any cost.
