SP.VS.810

Answer 1

The lower class boundary for the first class interval of 140-154 mm in a frequency table is 139.5 mm.

Step-by-step explanation:

The lower class boundary for the first class in a frequency table is the lowest value that you can have in that class interval. For the class interval of 140-154 mm, the lower class limit is 140 mm. However, to find the lower class boundary, we usually subtract 0.5 units from the lower class limit. Hence, the lower class boundary for the first class is 139.5 mm.

The lower class boundary for the first class can be calculated by subtracting 0.5 from the lower class limit. For the first class, the lower class limit is 140. Therefore, the lower class boundary is 140 - 0.5 = 139.5 mm.

The lower class boundary for the first class interval of 140-154 mm in a frequency table is 139.5 mm.
