Suppose a surveyor wants to conduct a phone survey about a new song. she plans to take a simple random sample. however, some people are on a do dash not dash call registry. do you believe this can affect the ability of the surveyor to obtain accurate polling results? if so, how? choose the correct answer below. a. yes, because it allows the surveyor to better target her intended demographic. b. yes, especially if the people who are on a do dash not dash call registry have a trait that is not accurately represented by the remaining people in the sample. c. yes, because it keeps the people who are less informed from introducing bias to the survey. d. no, this does not affect the surveyor's ability to obtain accurate polling results.

B) Yes, especially if the people who are on a do dash not dash call registry have a trait that is not accurately represented by the remaining people in the sample

If the person conducting the survey wants a good random sample then they should take opinions from a broad audience, including people from different backgrounds, races, ages, cultures etc. In this case, the people that are not on the call registry most likely have a common trait that would explain why they're not in there (ie. they're too young to be eligible to be in the call registry, they are too old to be on the call registry, etc). Not calling them then would throw off the sample. Because of this, B is the correct answer.

levels of production can be increased by technology while holding labor and capital constant, because increased technology makes the production process more efficient. subsequently, the lras curve is almost a vertical line, that can shift to the right, with an increase in technology.

the relationship between the lras curve and the ppc is that both can make the economy could grow. the ppc achieves that when it shifts outward because of more resources or technological advances while the lras curve shifts if more resources are developed or if there are technological advances.

the lras curve is a vertical line at an output level that represents the number of goods and services a nation can produce over a sustained period using all of its productive resources as efficiently as possible with all of the current technology available to it.

the production possibilities frontier (ppf) is a graphical device that is used for economic analysis of production decisions because the ppf measures the maximum possible combinations of two goods that an economy is capable of producing with its currently available resources and technology.
