Nicholas Zavala · Answer 1

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
