@phi

Answer 3

i will do state a...u can do b....put numbers in increasing order...
21 , 22 , 22 , 23, 23 ,23 , 24, 24, 25
Q2...middle number = 23
Q1..middle number of numbers before Q2 = (22 + 22) / 2 = 44/2 = 22
Q3..middle number of numbers after Q2 = (24 + 24)/2 = 48/2 = 24
minimum...lowest number = 21
maximum...highest number = 25
interquartile range = Q3 - Q1 = 24 - 22 = 2

Answer 4

okay give me a second

Answer 5

if there is 2 middle numbers...add them and divide by 2

Answer 6

IQR=1.5

Answer 7

for state b

Answer 8

right?
