Answer:
(a)29
(b)91cm
(c)13cm
Step-by-step explanation:
(a)From the graph, 11 men have a waist measurement of 85cm and below.
Since the cumulative frequency is 40
Number of men who have a waist measurement of more than 85 cm

(b)Median

Tracing 20 from the y-axis to the x-axis, the median waist measurement is 91cm.
(c)Interquartile Range
Interquartile Range = 

From the graph, at y=10, x=84 cm

From the graph, at y=30, x=97 cm
Therefore:
Interquartile Range=97-84=13cm
Answer:
