Answer:
2; 28.5 ; 34 ; 36 ; 38
Step-by-step explanation:
Given the data:
X = 25, 28, 29, 30, 34, 35, 35, 37, 38
n = 9
Values have been arranged in ascending order ;
The 5 number summary :
Maximum value : highest data value in the list = 38
Minimum value : Lowest data value in the list = 25
The lower quartile ; Q1 = 1/4(n+1)th term
Q1 = 1/4(10) th term = 2.5th term
Q1 = (2nd + 3rd) / 2 = (28+29)/2 = 28.5
Q2 = 1/2(n+1)th term
Q2 = 1/2(10) th term = 5th term
Q2 = 34
Q3 = 3/4(n+1)th term
Q3 = 3/4(10) th term = 7.5th term
Q3 = (7th + 8th) / 2 = (35+37)/2 = 36
Maximum value = 38 (highest data value in the list)
