a parameter.
25. A simple random sample of 50 students is taken from a local community college, which has a total of about 1500 students. Another simple random sample of 50 students is taken from a large state university, which has a total of approximately 20,000 students. The sampled students each answer a one-question survey which reads, “About how many MP3 songs do you own?” The sample average number of MP3 songs owned is calculated for the two sets of students. What can we conclude about the sampling variability in the sample average number of MP3 songs of the students sampled from the small community college as compared to that in the sample average of the students sampled from the large state university? It is impossible to make any statements about the sampling variability of the two sample means because the students surveyed came from different schools. The sample mean from the small community college has more sampling variability than that from the large state university because there are more students at the large state university. The sample mean from the small community college has about the same sampling variability as that from the large state university because the sample sizes are equal.Explanation / Answer
Answer:
The sample mean from the small community college has about the same sampling variability as that from the large state university because the sample sizes are equal.

A public opinion poll in Ohio wants to determine whether registered voters in the state approve of a measure to ban smoking in all public areas. They select a simple random sample of 50 registered voters from each county in the state and ask whether they approve or disapprove of the measure. The proportion of registered voters in the state who approve of banning smoking in public areas is an example of _________
Answer: Sample Proportion
3) The data in the sample size column can be considered
Answer: Statistic
1) A simple random sample of 50 students is taken from a local community college, which has a total of about 1500 students. Another simple random sample of 50 students is taken from a large state university, which has a total of approximately 20,000 students. The sampled students each answer a one-question survey which reads, “About how many MP3 songs do you own?” The sample average number of MP3 songs owned is calculated for the two sets of students.
