Answer 1

Answer:

22

Step-by-step explanation

N = 50 so N/2 = 25.

cf of 15-20 = 17 < 25 and cf of 20-25 = 37 > 25, and so

Median class = 20-25

Thus l = 20 h = 5 cf = 17 f = 20 N/2 = 25

Median =

$l + {(n \div 2 - cf) \div f} \times h$

Solve it and you will get Median = 22

Answer 2

answer:

@22@

Step-by-step explanation:

n=50 so n/2=25

cf of 15-20=17<25
