**Ms. Sue**, Wednesday, August 25, 2010 at 9:03pmI'm not sure what your instructor is looking for in this problem.

However, I see several things wrong with this scenario. First, it's unethical or maybe just poor practice to make cold calls before 9 a.m. Second, it's hard to believe that he reached all 50 voters in a two or three-hour period. The majority of voters are at work at this time of the morning.

Is there something else we should be discussing?

**sylvia**, Wednesday, August 25, 2010 at 9:27pmno, not the ethics, but from statistics stand point, what is wrong with reporting this as a legitimate survey? i dont understand the question either.

**Ms. Sue**, Wednesday, August 25, 2010 at 9:39pmIs 50 a large enough sample?

Are people listed in a phone book really a fair sample of registered voters?

Are phone calls likely to produce reliable results?

**Jen**, Wednesday, August 25, 2010 at 9:44pmMaybe it has something to do with the time he called? If he is calling all people without jobs, then it is not a representative sample.
