Given that a survey asked the question, "Do you think a vaccination should be mandatory to enter shopping areas?" to a random sample of 1068 Jordanians, and the results showed that 71.2% responded that vaccination should mandatory, to determine which of the following is an observation, a variable, a sample statistic (value calculated based on the observed sample), or a population parameter, the following statistical reasoning must be performed:

(a) A Jordanian that was asked the question.

-An observation, as the person questioned is part of the study and therefore, it is an individual observation that makes up the trend.

(b) The response of the Jordanian.

-A variable, since it is one of the two possible answers that the survey has.

(c) 71.2%.

-A population parameter, because it represents a specific percentage with respect to the total population.

(d) The percentage of all Jordanians who agreed with the statement that vaccination should be mandatory to enter shopping areas.

-A sample statistic, since it is a statistical element that arises from the survey.
