A surveyor wants to sample a city for the local Public Health Office in order to assess asthma rates annually. In order to get the best estimate for the project, the surveyor first decides to sample 2 of 15 census tracts, and then to sample 5 households from each tract. Assume there are only 10 households in each tract. The surveyor randomly assigns each tract in the city a number 01-15, and each household in each tract a number 01-10. Use the following random number table to select each tract, and then each household, continuing along the line. 058791 211403 098746 170528 086401 370614 097810 036418 340514 A) What kind of sampling strategy is this? B) Which census tracts and households will be selected?
Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
