Consider the hypothetical study described below. Based solely on the information given, do you have reason to question the resu
lts of the study? Explain your reasoning. A TV talk show host asks the TV audience, "Do you support new national mileage standards forautomobiles?" and asks people to vote by telephone at a toll-free number. Is there reason to question the results? A. No, there is not reason. The goal of the study is clear.
B. Yes, there is reason. The TV audience might not be representative of the population.
C. No, there is not reason. There is no bias in the study.
D. Yes, there is reason. The wording of the question might produce inaccurate or dishonest responses.
E. Yes, there is reason. Call-in polls tend to be biased.
F. No, there is not reason. It is unlikely that there are any confounding variables in the study.
B. Yes, there is reason. The TV audience might not be representative of the population.
Step-by-step explanation:
The question "Do you support new national mileage standards forautomobiles?" is asked to the TV audience.
Therefore those who will voted are the ones who are watching the TV show. We do not know the rate of people who do not watch TV or who do not watch that TV talk show in the population.
Thus the results cannot represent the whole population
The graph is symmetric with respect to the origin therefore it is on odd function. The graph is symmetric to the y- axis therefore it is an even function. The majority of functions are neither odd nor even, however, sine and tangent are odd functions and cosine is an even function.
