Final Answer:
The class interval corresponding to 51.5 is 46.5 - 51.5.
Explanation:
In a frequency distribution, class intervals are used to group data into ranges. To determine the class interval corresponding to a specific value, you need to identify the range within which that value falls.
In this case, the class marks are given as 26.5, 31.5, 36.5, 41.5, 46.5, 51.5, 56.5, and 61.5. These are the midpoints of the class intervals.
To find the class interval corresponding to 51.5, you look for the range that includes this value. In this list, the value 51.5 falls between 46.5 and 51.5.
Therefore, the class interval corresponding to 51.5 is 46.5 - 51.5.
This means that any data point between 46.5 and 51.5 (inclusive of 46.5 but not 51.5) would belong to this class interval.
