Forms of Christianity have dominated religious life in what is now the United Kingdom for over 1, years. The doctrine of Pelagianismdeclared heretical in the Council of Carthageoriginated with a British-born ascetic, Pelagius. The Anglo-Saxon invasions briefly re-introduced paganism in the 5th and 6th centuries; Christianity was again brought to Great Britain by Catholic Church and Irish-Scottish missionaries in the course of the 7th century see Anglo-Saxon Christianity. Still in the Anglo-Saxon period, the archbishops of Canterbury established a tradition of receiving their pallium from Rome to symbolize the authority of the Pope.
Explain how a sample differs from a population. Give an example of a population and two different characteristics that may be of interest.
Illustrate with an example. Identify each of the following data sets as either a population or a sample: The grade point averages GPAs of all students at a college. The GPAs of a randomly selected group of students on a college campus. The gender of every second customer who enters a movie theater.
The lengths of Atlantic croakers caught on a fishing trip to the beach. Identify the following measures as either quantitative or qualitative: The last four digits of social security numbers of all students in a class.
A researcher wishes to estimate the average amount spent per person by visitors to a theme park. What is the population of interest?
What is the parameter of interest? Based on this sample, do we know the average amount spent per person by visitors to the park? A researcher wishes to estimate the average weight of newborns in South America in the last five years.
Based on this sample, do we know the average weight of newborns in South America? A researcher wishes to estimate the proportion of all adults who own a cell phone.
What is the statistic involved? Based on this sample, do we know the proportion of all adults who own a cell phone? A sociologist wishes to estimate the proportion of all adults in a certain region who have never married. Based on this sample, do we know the proportion of all adults who have never married?
What must be true of a sample if it is to give a reliable estimate of the value of a particular population parameter? Answers A population is the total collection of objects that are of interest in a statistical study. A sample, being a subset, is typically smaller than the population.
In a statistical study, all elements of a sample are available for observation, which is not typically the case for a population.
A parameter is a value describing a characteristic of a population. In a statistical study the value of a parameter is typically unknown. All currently registered students at a particular college form a population.CHAPTER 6: STATISTICS DIAGNOSTIC TEST 1.
