Explanation / Answer
we need to make the class continuos first by subtracting 0.5from the lower limit of the class and adding 0.5 to the upper limitof the class as follows: Class Boundaries class intervals Frequency 1-4 0.5-4.5 2 5-8 4.5-8.5 5 9-12 8.5-12.5 7 13-16 12.5-16.5 10 17-20 16.5-20.5 2 Class Boundaries class intervals Frequency 1-4 0.5-4.5 2 5-8 4.5-8.5 5 9-12 8.5-12.5 7 13-16 12.5-16.5 10 17-20 16.5-20.5 2 Class Boundaries class intervals Frequency 1-4 0.5-4.5 2 5-8 4.5-8.5 5 9-12 8.5-12.5 7 13-16 12.5-16.5 10 17-20 16.5-20.5 2
