Answer #1

Parameter is function of population values.

Suppose You know that in a certain city the height of people are normally distributed with mean (or any distribution it may follow). You are interested to know the average height of people of that city. Here is the average height of population and is the unknown parameter.

Now it is not possible for you to measure height of each and every person in that city.Hence you need to estimate the unknown population mean by taking some sample from the population.

So, In a nutshell anything that is a function of population is a parameter. It is not possible to enumerate each and every population member to know the true value of parameter and hence estimation is required.

You would like to estimate a population proportion p. For example, this might be the proportion of all undergraduate students who own iPhones. You take a sample of size n and discover the sample proportion p̂, the proportion of students in the sample who own iPhones. Assume that p=0.36 and n=500. Which of the following is true? a. If you took many samples of size 500 from this population and calculated a sample proportion p̂ for each, the standard deviation...

Confidence intervals seek to estimate a population parameter with an interval of values calculated from an observed sample statistic. Demonstrate that you understand this concept by describing a situation in which one could use a sample mean or sample proportion to produce a confidence interval as an estimate of a population mean or population proportion. I am asking you to make up a situation where a confidence interval might be computed. Clearly identify the population, sample, parameter, and statistic involved...

I would like you to estimate the population proportion of adults without children that visit the local zoo. 500 total, children included, visit the zoo each day.
