Solution
The correct option is D Can't be determined
This is grouped data frequency distribution. Individual height of person can't be determined from this frequency distribution.
The number of people having exactly 149.5 and 169.5 cannot be determined by this but this can be done by ungrouped frequency distribution.
From this distribution, we can only get the number of people having height in the range of 149.5 and 169.5.
