Answer:

Median = 27.5

Step-by-step explanation:

Arrange it in increasing order

Arrange it in increasing order7, 13, 15, 18, 20, 20, 25, 30, 30, 33, 35, 40, 45, 55

Arrange it in increasing order7, 13, 15, 18, 20, 20, 25, 30, 30, 33, 35, 40, 45, 55Number of terms (n) = 14

Arrange it in increasing order7, 13, 15, 18, 20, 20, 25, 30, 30, 33, 35, 40, 45, 55Number of terms (n) = 14 Median = ((n/2)th term +(n/2+1)th term) ÷2

Arrange it in increasing order7, 13, 15, 18, 20, 20, 25, 30, 30, 33, 35, 40, 45, 55Number of terms (n) = 14 Median = ((n/2)th term +(n/2+1)th term) ÷2 = ((14/2)th term +(14/2+1)th term) ÷2

Arrange it in increasing order7, 13, 15, 18, 20, 20, 25, 30, 30, 33, 35, 40, 45, 55Number of terms (n) = 14 Median = ((n/2)th term +(n/2+1)th term) ÷2 = ((14/2)th term +(14/2+1)th term) ÷2 = (7th term + 8th term) ÷2

Arrange it in increasing order7, 13, 15, 18, 20, 20, 25, 30, 30, 33, 35, 40, 45, 55Number of terms (n) = 14 Median = ((n/2)th term +(n/2+1)th term) ÷2 = ((14/2)th term +(14/2+1)th term) ÷2 = (7th term + 8th term) ÷2 =(25 +30) ÷2

Arrange it in increasing order7, 13, 15, 18, 20, 20, 25, 30, 30, 33, 35, 40, 45, 55Number of terms (n) = 14 Median = ((n/2)th term +(n/2+1)th term) ÷2 = ((14/2)th term +(14/2+1)th term) ÷2 = (7th term + 8th term) ÷2 =(25 +30) ÷2 = (55) ÷2
