Answer:
140 and 70
Explanation:
the range is the difference between the largest and smallest values.
the largest value at the right end of the line is 190
the smallest value at the left end of the line is 50
then
range = 190 - 50 = 140
the interquartile range is the length of the box , so
interquartile range = 150 - 80 = 70
