2. death certificates are used as the basis for measuring the number of deaths and the probability of death among infants.

1. Mad cow disease is diagnosed in a cow and the entire herd is subsequently slaughtered. Single case or small number of cases

2. Death certificates are used as the basis for measuring the number of deaths and the probability of death among infants. Statistics—vital statistics and reportable diseases

3.  A sample of adolescents are questioned about their cigarette smoking behavior. Survey data

Explanation:

As we can see that the Mad cow disease was diagnosed in just a single cow first hence this type of data illustrates single case or small number of cases.

Statistics are used for numbering the amounts of dead which might have occurred in a region or entire country during a particular time. The statistics can be compared with one another. Hence, the data for death would be calculated by statistics- vital statistics and reportable diseases.

A survey is used to ask a question or different questions from people under study. Hence, the data from a sample of adolescents questioned about their cigarette smoking behavior would be a survey.
