Answer 1

17.5

Explanation:

70, 80, 85, 90, 95

Median: 85

Lower quartile: 75

Upper quartile: 92.5

Interquartile range: 92.5 - 75 = 17.5

Answer 2

median=85 since it is the middle data point
Q1= 80 because it is the middle of the left side of the median
Q3=90 since it is the middle of the right side of the median
IQR= Q3-Q1=90-80=10
