Final answer:
The lower limit of a class interval can be found by subtracting the width of the interval from the upper limit. In this case, the width of the interval is 12 and the upper limit is 25. Therefore, the lower limit can be calculated as 25 - 12 = 13.
Step-by-step explanation:
The upper limit of a class interval is 25 and the width is 12. To find the lower limit, we subtract the width from the upper limit:
Lower limit = Upper limit - Width
Lower limit = 25 - 12
Lower limit = 13
Therefore, the lower limit of the class interval is 13.
