To draw a histogram to represent the following frequency distribution. The adjusted frequency for the class is :
Class interval | 5-10 | 10-15 | 15-25 | 25-45 | 45-75 |
Frequency | 6 | 12 | 10 | 8 | 15 |
Adjusted frequency of a class is given by,
Therefore,
Adjusted frequency for the class
Hence, the correct answer is (D)
