Part A
we have that
Jake
Median=86
Q3=90
Q1=80
IQR=90-80=10
Ryan
Median=75
Q3=85
Q1=70
IQR=85-70=15
so
Ryan's median test score is less than Jake's median test score
The interquartile range of Ryan's test score is greater than the interquartile range of Jake's test score
Part B
The answer is
less than and less
