Answer:
a) Range =10
b) inter quartile range = 4.5
Step-by-step explanation:
Explanation:-
Given minimum =5
Median=8
upper quartile (Q3) =11.5
Lower quartile range= 7
Maximum=15
a) Range = maximum value -minimum value
= 15 -5
= 10
b) Interquartile Range = median of upper half - median of lower half
= Q₃- Q₁
= 11.5 - 7
= 4.5
