Range is defined as = upper value - lower value.
Now here in this question, the upper value is not clearly mentioned.
for 22% of employees , 6 or more errors can be 7 as well as 10.
So the range will be 7-0 = 7 OR 10-0=10.
Hence we do not have clear value and so can't determine the range with the given info.
Answer E
