C On average, a computer technician at Company B earns more than at Company A.
The mean at B is 56 k
the mean at A is 58 k
Therefore on average B does NOT make more than A.
HOWEVER the RANGE for A , 22 k, is greater than the RANGE for B , 17 k
Therefore choice A is it.

You are correct. The statement "On average, a computer technician at Company B earns more than at Company A" is incorrect. The mean salary at Company A is actually higher than the mean salary at Company B. The correct statement would be that the range of salaries for computer technicians at Company A is greater than the range of salaries at Company B.
The range is a measure of how spread out or varied a set of data is. It is calculated by subtracting the minimum value from the maximum value. In this case, the range for Company A is $22,000 ($63,000 - $41,000) and the range for Company B is $17,000 ($62,000 - $45,000). This means that the salaries for computer technicians at Company A vary more widely than the salaries at Company B. Therefore, statement A is true.
