define the term population ,sample parameters

Expert Solution

Population: In statistics, a population is the entire pool from which a statistical sample is drawn.The population or the aggregate of individuals to which the survey results would apply, must be clearly and unambiguously defined. The geographical, demographic and other boundaries of the population must be specified so that no ambiguity arises regarding the coverage of the survey. For example: a population maybe an entire group of people, objects, events, measurements etc.

Sample: The part of the population selected by sampling is called a sample.

Example: Let's say there were 200,000 test-takers who sat for the GRE exam in 2019. The random sample of size 1000 drawn from this population.

Parameters: A parameter is a numerical quantity that characterizes a given population or tells us something about the whole population. For example, population mean, population standard deviation etc are parameters.

Define the term “population” in ecology: In this assignment we will be discussing the species of honey bees; come up with an example of a honey bee population (Make sure to use the ecological meaning of the term “population:” Do you think honey bees are K-selected or r-selected species? Explain. Honey bees are keystone species. Define the term “keystone species” and explain why it applies to honey bees:

We use sample data to estimate population parameters and point estimate and interval estimate are two typical tools of such estimation. Please discuss them answering the following questions. 1) Briefly discuss about how point estimate and confidence interval are different to each other. 2) Discuss about way(s) to secure unbiased and efficient point estimators. 3) Discuss about the effects of confidence level (or, Z-score) and sample size on the width of confidence interval. Is it good or bad to have...

2. In terms of estimating population parameters using sample statistics, one would think that the highest level of confidence in an estimate (in other words, the 99% confidence level) would always be preferred by researchers. A. What is/are the advantage(s) of reporting a confidence interval at the 99% confidence level? B. Explain why researchers might rather choose a lower level of confidence (say the 95% or 90% confidence level) in their estimation of confidence intervals. Show all work, do not...
