Problema Solution
In a random sample of 400 people from a city, 120 are ladies. Can it be said that the men and ladies are in the ratio 5:3 in the population
Answer provided by our tutors
number of ladies: 120
number of men: 400 - 120 = 280
the number of men to the number of ladies is
280/120 = 7/3
the men and ladies are in the ratio 7:3 - NOT in the ratio 5:3.
