Answer 1

a) The Percentile of the age of 50 years

Percentile of the data = (No. of women less than 50years/ Total number of women) * 100

= (77/87)*100 = 88.51

Answer : Percentile of the age of 50 is 86

b)

The Percentile of the age of 25 years

Percentile of the data = (No. of women less than 25 years/ Total number of women) * 100

= (5/87)*100 =5.75

Answer : Percentile of the age of 25 is 6

c)

The Percentile of the age of 80 years

Percentile of the data = (No. of women less than 80 years/ Total number of women) * 100

=(86/87)*100 = 98.85

Answer: Percentile of the age of 80 is 99
