*There are two different answers posted. Other students were asked the same question. Which response is correct?

Thank You :0)

The population of drivers has a μ = 10 and σ = 20 speeding tickets. If we randomly select (with replacement) a sample of n=400 from the population, how well (on average) will the sample represent the population? In other words, how far off (on average) will you expect your sample mean to be from the population mean?

1. 0.05

2. 20

3. 2

4. impossible to determine without the sample mean

    Two researchers conducted a study in which two groups of students were asked to answer 42 trivia questions from a board game. The students in group 1 were asked to spend 5 minutes thinking about what it would mean to be a professor, while the students in group 2 were asked to think about soccer hooligans. These pretest thoughts are a form of priming. The 200 students in group 1 had a mean score of 26.2 with a standard deviation...

    It is known that nationally, students attending four-year colleges get an average of 6.75 hours of sleep per night, with a standard deviation of 1.7 hours. You are interested in seeing if students who attend commuter colleges (colleges where students must commute to school because there are no dorms on campus), such as John Jay College of Criminal Justice, differ significantly from this national average. Complete the following steps in order: What are the population mean and population standard deviation?...

    1. One way of exposing under-coverage, non-response and other sources of error in sample surveys is to compare the results with known facts about the population. According to the 2010 US Census, about 1.6% of the population of the USA is Native American so the number of Native Americans in large random samples should vary approximately Normally. (a, b) What are the criteria for assessing whether a binomial sample can be approximated by a Normal distribution? (c) Based on those...
