There are 40000 homes in a city. These can be divided into 3 categories:
• Privately owned: 12000
• Rented from companies: 8000
• Rented from private landlords: 20000.
How many homes from each category should be included in a stratified sample of size 100?

Definition Definition Number of subjects or observations included in a study. A large sample size typically provides more reliable results and better representation of the population. As sample size and width of confidence interval are inversely related, if the sample size is increased, the width of the confidence interval decreases.
