Please Help!!!

Answer 1

A) About 25% of the fishermen caught between 25 and 30 fish.
 >Since the boxplot looks symmetric, the parts are each 25%. 

B) The spread is symmetrical about the median.
 >The median is 20. 
20-15 = 5; 15-10 = 5
25-20 = 5; 30-25 = 5

E) The range is 20 fish.
 > The largest data is 30, smallest data is 10
Range = largest - smallest = 30-10 = 20
