<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.

In order for the heat to be transferred from the body X to the body Y via conduction, there must be a difference in temperature of body X with respect to body Y. Body X must have a higher temperature than body Y. This process continues until both bodies arrive at thermal equilibrium, meaning they both have the same temperature.
Answer:
0.10839 m
Explanation:
= Atmospheric pressure = 1 atm = 101325 Pa
= Total pressure at bottom of mecury = 1.2 atm
g = Acceleration due to gravity = 9.81 m/s²
h = d = Depth of mercury
= Density of mercury = 
= Density of water = 
Pressure at the bottom is of the cylinder is given by
Pressure at the bottom of mercury is
The depth of the mercury is 0.10839 m
Answer:
F = 0.64 N
Explanation:
We are given;
Spring constant constant; k = 1.28 N/m
Distance; x = 0.5 m
From Hooke's law, we know that F = kx.
Thus;
F = 1.28 × 0.5
F = 0.64 N
Thus, force it takes to pull the spring back = 0.64 N
