question
which of the following is continuous data?
select all correct answers.
select all that apply:
the 2015 cdc family growth survey also asked women how many whole cigarettes they smoked per day.
a survey management company measured how much time each participant takes to complete a survey.
an environmental researcher measured the average length of the fish in a certain lake.
a librarian counted the number of books returned in a day.

Explanation:

1. Recall the definition of continuous data: data that can take any value within a range (not just whole numbers, e.g., time, length can have decimals).
2. Analyze each option:

• "Number of whole cigarettes smoked per day": This is discrete (only whole numbers, can't smoke a fraction of a whole cigarette in this context).
• "Time to complete a survey": Time can be measured in fractions (e.g., 2.5 minutes), so continuous.
• "Average length of fish": Length can be measured in fractions (e.g., 3.2 cm), so continuous.
• "Number of books returned": Discrete (only whole numbers, can't return a fraction of a book).

Answer:

B. A survey management company measured how much time each participant takes to complete a survey.
C. An environmental researcher measured the average length of the fish in a certain lake.
