Answer:
Public :
Q1 = 27.5
Q2 = 31.5
Q3 = 36
Private:
Q1 = 33.5
Q2 = 37.5
Q3 = 38.5
Step-by-step explanation:
Given the data:
Public Transportation
23 25 25 30 31 31 32 33 35 38 37 42 ;
Rearranged data :
23, 25, 25, 30, 31, 31, 32, 33, 35, 37, 38, 42
Median :
1/2(n+1)th term
n = sample size = 12
1/2(13)th term = 6.5th term
(6th + 7th)/ 2
(31 + 32) / 2 = 31.5
1st quartile :
1/4(n + 1)th term
1/4(13) th term.
Q1 = 27.5
3rd quartile :
3/4(n + 1)th term
3/4(13) th term.
Q3 = (25 + 37) / 2 = 36
Private
32 32 33 34 37 37 38 38 38 39 40 44
Rearranged data:
32, 32, 33, 34, 37, 37, 38, 38, 38, 39, 40, 44
Median :
1/2(n+1)th term
n = sample size = 12
1/2(13)th term = 6.5th term
(6th + 7th)/ 2
(37 + 38) / 2 = 37.5
1st quartile :
1/4(n + 1)th term
1/4(13) th term.
Q1 = 33.5
3rd quartile :
3/4(n + 1)th term
3/4(13) th term.
Q3 = 38.5
