Question

Question 6 (1 point) Let us say we have two colleges, one is private, the other is a public school. The private school has 5000 students attending while the public school has 40,000 students attending. On the issue of supporting the use of marijuana both student bodies are, for practical purposes, the same. This means that some student support, some don't, some don't care, but the proportions of any category you can dream with regards to this issue, at each school, are identical. Now a researcher wants to find out what the prevalent thought is at each school, and wants to estimate the proportion of students at each school that support upcoming legislation that will decriminalize the use of marijuana. The question concerns the sample size required for each school in order to get a representative result. If 400 students are chosen at random using a simple random sample to participate in a survey from the private school, will the sample size at the public school need to be the same, less than, greater or not possible to know, than the private school sample size in order to get the same level of accuracy in the statistic we generate from the sample? The same, n 400 Less than, n 400 Not possible to know,n-?

Explanation / Answer

Answer: D

That is, not possible to know, n = ?

Since using simple random sample to select the sample from the population then the sample size is not known.
