<u><em>[NOTE: THIS IS INCOMPLETE QUESTION. THE COMPLETE QUESTION: 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.]</em></u>
In method I, the population generalization is almost random, hence it uses a random sample. In method II, the population generalization is less random, hence it uses a biased sample.
In terms of population generalization, the two methods differ. In method I where participants randomly assign each participant to exercise with a training partner or to exercise alone from the volunteers who are willing to participate, the sampling method is almost random as it includes people who are exercise regularly (in majority) and those who do not exercise regularly. Due to the randomized nature of the sample, the results can be applied to the entire population.
In method II where sampling is done by selecting a random sample of people from all the people who exercise at a community fitness center and determining if they use a training partner or exercise alone to create the two groups. As the people included in the sample are less random as they work out regularly at the fitness center. Hence, the sample is biased as it does not include any representation of people who do not work out regularly. The results cannot be used to apply to the entire population generalization.
Therefore, Population generalization is generalizing the population into two categories out of which one is more random in selection than the other.

Which were difficulties that the builders of the transcontinental railroad found ways to overcome? Select all the choices that apply.
Answer: Out of all the options presented above the ones that represent the difficulties that the builders of the transcontinental railroad found ways to overcome are answer choices A) providing supplies to build the tracks and support the workers and B) natural barriers such as mountains, rivers, and forests. It was also the same reason why the transcontinental railroad was being constructed. It would help the transportation of if this is hitory i dont know what subject this is but if its history heres the answers
Answer:
almost 100% positive its B but dont take me up on it
<h2>If the distance between Earth and moon is increased , the gravitational force will decrease by a proportional amount .</h2><h2>The iron filings sprinkle around the magnet are arranged in regular pattern . The reason for this is that magnet can attract magnetic substances through various materials .</h2>
Explanation:
If the distance between Earth and moon is increased , the gravitational force will decrease by a proportional amount .
The iron filings sprinkle around the magnet are arranged in regular pattern . The reason for this is that magnet can attract magnetic substances through various materials .
