Answer:
difference in the proportion = 0.0452
Step-by-step explanation:
x1 = 27, n1 = 193,
p1 = 27/193
p1 = 0.1399
x2 = 16, n2 = 169,
p2 = 16/169
p2 = 0.0947
a) The best estimate for the difference in the proportion of smokers, using male proportion minus female proportion is 0.0452. Male smokes more than females in given sample.
p1 - p2 = 0.1399 - 0.0947
p1 - p2 = 0.0452
