Researchers are investigating whether people who exercise with a training partner have a greater increase, on average, in targeted exercise intensity compared with people who exercise alone. Two methods of collecting data have been proposed.

Method I: Recruit volunteers who are willing to participate. Randomly assign each participant to exercise with a training partner or to exercise alone.
Method II: Select a random sample of people from all the people who exercise at a community fitness center. Ask each person in the sample whether they use a training partner, and use the response to create the two groups.
(a) For each method, the researchers will record the change in targeted exercise intensity for each person in the investigation. They will compare the mean change in intensity between those who exercise with a training partner and those who do not.

(i) Describe the population of generalization if method I is used. Explain your answer.
we could generalize to all the people who work out a gyms?

(ii) Describe the population of generalization if method II is used. Explain your answer.
The population would only be those at the fitness center, we could not generalize for the whole pop. of people who exercise at the gym?

how u gonna have the problem and not the answer???

i) Pop - generalize the pop of people who work out at gyms?

(i) If method I is used, the population of generalization would be all the people who volunteer to participate in the study. The researchers randomly assign each participant to either exercise with a training partner or to exercise alone. Therefore, the findings would be applicable only to the population of volunteers who are willing to participate in the study, rather than being representative of all people who work out at gyms. It's important to note that the findings may not be applicable to individuals who choose not to participate in the study.

(ii) If method II is used, the population of generalization would be limited to the random sample of people selected from the community fitness center. The researchers would ask each person in the sample whether they use a training partner, and based on their responses, create two groups - those who exercise with a training partner and those who exercise alone. Therefore, the findings would only be applicable to the population of people who exercise at the community fitness center and may not be representative of the whole population of people who exercise at other gyms or fitness centers.

We do not do your homework for you. Although it might take more effort to do the work on your own, you will profit more from your effort. We will be happy to evaluate your work though. What are your answers?
