Question

) If the median of the distribution given below is 24, find the value of x. Age (in yean 0-10 10-20 20-30 30-40 40-50 No. of people 5 25 Х 18 7
​

Answer 1

Answer:

65

Step-by-step explanation:

5+25+x+18+7/5=24

5+25+x+18+7=24x5

55+x=120

x=120-55

x=65

Answer 2

Answer: The missing frequency is 25.

Step-by-step explanation:

The given median is 24,

∴The median class is 20-30 &

 / = 20, ℎ = 10, = 55 + , = = 30

= +[(N/2 -cf)/f] x h

=>24= 20 + [(55+x)/2-30)/x] x 10

=>24-20 = [(55+x-60)/(2x)] x 10

=>4= [(x-5)/(2x)] x 10

=> 8 = 10-50

=>2 = 50 => = 25

Thus, the missing frequency is 25.
Hope it helps.
