Detailed explanation-1: -Answers. B is discrete because the numbers of brothers and sisters can only be values like 0, 1, 2 etc.
Detailed explanation-2: -Examples of discrete data Some discrete data examples are: The number of customers who bought different items. The number of computers in each department. The number of items you buy at the grocery store each week.
Detailed explanation-3: -A discrete quantitative variable is one that can only take specific numeric values (rather than any value in an interval), but those numeric values have a clear quantitative interpretation. Examples of discrete quantitative variables are number of needle punctures, number of pregnancies and number of hospitalizations.
Detailed explanation-4: -Discrete data is a count that involves integers-only a limited number of values is possible. This type of data cannot be subdivided into different parts. Discrete data includes discrete variables that are finite, numeric, countable, and non-negative integers.
Detailed explanation-5: -So only c, only the number of miles between any 2 cities is not an example of discrete data c is the correct answer to this question.
