Question

In a certain city 250 men in a sample of 1000 were found to be smokers. in anotherr city the numbar of smokers was 750 in a random sample of 2000. does this indicate the there is a greater proportion of smokers in the second city than in the first?

Answer 1

ratio in the first sample = 250/1000 = 1/4 = 0.25
ratio in the second sample = 750/2000 = 0.375

hence , there is a greater proportion of smokers in the second city than in the first.

hope this helps!!
