Question

The class intervals in a frequency distribution are: 40-44,45-49,50-54,55-59. If the frequency distribution is converted into continuous frequency distribution then the class intervals are​

Answer 1

Given frequency distribution: $40-44,45-49,50-54,55-59.$

Solution:

Know that, We can convert the given frequency distribution into continuous frequency distribution by subtracting$0.5$ from the lower limit of the class intervals and adding $0.5$ to the upper limit of class intervals in each interval.

Hence, the Continuous frequency distribution is given as follows:
