Answer

The class boundaries for the first class are:-0.005 and 0.995, and for the second class:0.995 and 1.995.

Work Step by Step

The upper class boundary is: 0.99+ (1-0.99)/2=0.995, the lower class boundary is:0.995-1=-0.005, but weight cannot be negative. Therefore the class boundaries for the first class are:-0.005 and 0.995, and for the second class:0.995 and 1.995.
