Question

Find the lower class boundary for the class whose limits are 10−15 Answer

1. 9.5
2. 10
3. 9
4. 10.5

Answer 1

The lower class boundary for the class with limits 10−15 is 9.5, found by subtracting 0.5 from the lower limit.

Step-by-step explanation:

The lower class boundary for the class with limits 10−15 is found using the concept of class boundaries in frequency distributions. Since the class limits are given as whole numbers, we insert a class boundary between them and the adjacent classes by subtracting 0.5 from the lower limit. The lower class boundary for this class, therefore, is 10 - 0.5, which equals 9.5.
