During each summer, many families spend part of their vacation time at a beach along the East or West Coast. Due to the popularity of movies like Jaws and The Shallows, and publicity about recent shark attacks on surfers, swimmers, snorkelers, and spearfishermen, Americans have become increasingly concerned about water activities. Research suggests that 58% of all shark attacks involve surfers. One thousand records of shark attacks are selected, and each is categorized by the victim group. Identify the population, sample, and variable for the study. Population Sample Variable
a. all families who spend part of their vacation at a beach along the East or West coast
b. Americans who are concerned about water activities
c. the percentage of shark attacks that involve surfers
d. the set of groups to which the victims of shark attacks belong
e. all shark attacks
f. the 1000 records of shark attacks that were examined

Population = e. all shark attacks.

Sample = f. the 1000 records of shark attacks that were examined.

Variable = d. the set of groups to which the victims of shark attacks belong.

Step-by-step explanation:

The population in a particular study refers to the entire set of people to which the research study encompasses, that is all those who are eligible to be a part of the study or those who the study relates to and the outcome of the study Cann be applied to them. In the research study described above, the population of the study is all events of shark attacks.

The sample is a subset of the larger population ; the subset selected in the scenario above is the 1000 records examined out of all the events of shark attacks.

The variable in the study may refer to a set of independent variables which is according to the scenario is the set of groups to which victims of shark attack belong.
