Chapter 7
It isn't easy to measure a parameter such as the mean height or the mean weight of a population. So, we draw samples from the population and calculate ...
Collecting samples or responses from an entire population takes significant time and effort, so a researcher collects responses from only a sample of that ...
An unbiased point estimate is often insufficient to predict a population estimate, such as population mean or population proportion. In this scenario, a ...
The confidence coefficient is also known as the confidence level or degree of confidence. It is the percent expression for the probability, 1-α, that ...
A confidence interval is a better estimate of the population than a point estimate, as it uses a range of values from a sample instead of a single value. ...
A critical value is a definite value obtained from a particular probability distribution at a predecided confidence level (or a predecided significance ...
The margin of error is also called the maximum error of an estimate. The margin of error is the maximum possible or expected difference between the ...
Knowledge of the sample size is the first requirement to conduct random sampling or an experiment. The sample size is the total number of units, ...
To construct a confidence interval for a single unknown population mean μ, where the population standard deviation is known, we need sample mean as ...
In practice, we rarely know the population standard deviation. In the past, when the sample size was large, this did not present a problem to ...
A point estimate of the population mean is obtained from a single sample. Such a point estimate does not represent a population well because it needs to ...
