Is it possible to identify the exact values of all of the original service tímes?
OA. Yes. The data values in each class are spread evenly across the full length of the class.
O B. No. The data values in each class could take on any value between the class limits, inclusive.
C. No. The frequency distribution tells nothing about the data values that fall below the lowest
class limit or above the highest class limit.
D. Yes. The data values in each class are equal to the corresponding class midpoint.
