If a frequency distribution for the number of persons x in a household is prepared with class intervals (1−4),(5−8),(9−12) etc., then the number of persons x belonging to class interval (5−8) satisfies.

The correct option is D 5≤x≤8Since the intervals need to include the values of the limits too, answer is 5≤x≤8.
