Student Attitudes About The Recreational Services

The population sampled due to its specific nature i.e., college students, and college graduates would need to be contemplated in regards to the testing results as it is offered as a depiction of the general population.

- Because all available data was used, there is a greater sample in our analysis. We assume that more data points will lead to a more accurate conclusion.

12. _____ For a given population, confidence intervals constructed from larger samples tend to be narrower than those constructed from smaller samples. Which statement below best describes why this is true? (A) The variability of the sample mean is less for larger samples. (B) The z-value for larger samples tends to be more accurate. (C) The population variance is larger for large populations. (D) As the sample size increases, the z-value (or t-value) becomes smaller. A machine dispenses potato chips into bags that are advertised as containing one pound of product. To be on the safe side, the machine is supposed to be calibrated to dispense 16.07 ounces per bag, and from long time observation, the distribution of the fill-weights is known to be approximately normal and the process is known to have a standard deviation of 0.15 ounces.

The sample is not a representative of the population. The number of different groups of nurses was not equal. Registered nurses had the biggest number and this made the research biased towards them (Kalisch & Lee, 2011, p. 86). To represent the entire population, the different

2. Choose one of the research questions from above and consider it in more detail. Based upon the question, what would be a reasonable hypothesis?

8. The people who make up this article is the students from 7 different universities. It was rather representative because they were from universities that were located across the US, not just from one specific area. This was a unsystematic selection procedure because they weren’t from specific groups or students, just casual students from the seven different universities which created a representative sample of a big population.

10. Was the sample for this study adequately described? Provide a rationale for your answer.

3. Sample Population: Who exactly was used in the study? How many? (Be as specific as possible.)

This sample may have a bias resulting from subjects that have a special interest in the subject being studied.

10) Was the sample for this study adequately described? Provide a rationale for your answer

2.Why was it important to address this question? Why do we need to know the answer to this research question?

5) Select the study that is most appropriate and EXPLAIN WHY it is most appropriate for the study.

b) An investigation of 150 randomly selected local restaurants concluded that 42% of local restaurants have serious health code violations. Is this a population or a sample; explain your answer. Sample, because it is the study of a much smaller group of people.

The sample size is chosen to maximise the chance of uncovering a specific mean difference, which is also statistically significant. The reason larger samples increase your chance of significance is because they more reliably reflect the population mean. Therefore it is necessary to conduct any survey or interview with as many

a. Conclusion drawn must be based on a sample that represent the entire group .
