How do we tell if the median of two populations are different?
Review of Confidence intervals
How we can use the confidence interval for the difference between the two population means (or medians) to draw a conclusion
Is zero contained in the confidence interval?
You must make an inference, which will be a conclusion about the population medians based on their samples taken from the population.
Your conclusion will answer the posed investigative question and will involve making a call about the population medians.
The informal confidence intervals will be used to make an inference about the population medians.
How can we answer our question:
What can we conclude?
How does Population A compare to Population B?
