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
