Question

a magazine ran a survey about a web site for downloading music. readers could register their responses on the magazine’s web site. identify what is wrong. choose the correct answer below. a. the sample is a voluntary response sample, so there is a good chance that the results do not reflect the population. b. it is likely that the survey used a loaded question, so the results of the survey are not reliable. c. the sample is a census, so there is a good chance that the results do not reflect the population. d. the magazine has an interest in the survey results, so the source of the survey is questionable.

Explanation:

A voluntary response sample is when people choose to respond (like readers registering responses on the magazine's website). Such samples often have bias because those with strong opinions or interest are more likely to respond, so results may not reflect the whole population. Option B talks about loaded questions (not indicated here), C says it's a census (census is all population, here it's a sample of volunteers), D says the source is questionable due to interest, but the main issue is the voluntary response sample. So A is correct as voluntary response samples have high chance of non - representative results.

Answer:

A. The sample is a voluntary response sample, so there is a good chance that the results do not reflect the population.
