Answer:
13420
Step-by-step explanation:
Salary No.of persons c.f
5-10 49 49
10-15 133 49+133 = 182
15-20 63 182+63 = 245
20-25 15 260
25-30 6 266
30-35 7 273
35-40 4 277
40-45 2 279
45-50 1 280
Median = (N/2)th term
= (280/2)
= 140.
Median class = 10-15
Cf = 49, f = 133, l = 10, h = (15 - 10) = 5
Median = l + (N/2 - cf/f) * h
= 10 + (140 - 49/133) * 5
= 10 + (91/133) * 5
= 13.42.
So, the salary in thousands = 13.42 * 1000
= 13420.
Hence,Median salary of the data = 13420.
Hope it helps you
