Answer:
Boxplot A
Step-by-step explanation:
Given the data:
22, 25, 50, 58, 28, 24, 25, 51, 43, 32, 49, 38
We should obtain the 5 number summary and check which boxplot correctly displays the information :
Reordered data : 22, 24, 25, 25, 28, 32, 38, 43, 49, 50, 51, 58
. Maximum = 58
Minimum = 22
Lower quartile : 1/4(n+1)th term
n = 12
1/4(13)th term = 3.25
(3rd + 4th) = (25 + 25) /2 = 25
Median :
1/2(13)th = 6.5th term
(32 + 38) /2 = 35
Upper quartile :
3/4(13)th term 9.75 term
(49 + 50) / 2
= 49.5
