The best choice of classes is (c)

From the parameters, the range of the histogram is:

Range = 0.319 to 0.366

Subtract the least from the highest

Range = 0.366 - 0.319

Range = 0.047

Divide by 6 to determine the class width

Width = 0.047/6

Width = 0.009

So, we have the following classes

0.310 -0.319,.........., 0.360 -0.369

Hence, the best choice of classes is (c)
