Answer:
So, we conclude that the best estimate for the difference in the proportion of smokers is 4.4%.
Step-by-step explanation:
We know that 27 of the 193 males in the sample smoke while 16 of the 169 females in the sample smoke.
We have the following proportion:
![27:x=193:100\%\\\\193x=27\cdot 100\\\\193x=2700\\\\x=\frac{2700}{193}\\\\x=13.9\%](https://tex.z-dn.net/?f=27%3Ax%3D193%3A100%5C%25%5C%5C%5C%5C193x%3D27%5Ccdot%20100%5C%5C%5C%5C193x%3D2700%5C%5C%5C%5Cx%3D%5Cfrac%7B2700%7D%7B193%7D%5C%5C%5C%5Cx%3D13.9%5C%25)
So we get that 13.9% of men smoke.
We have the following proportion:
![16:x=169:100\%\\\\169x=16\cdot 100\\\\169x=1600\\\\x=\frac{1600}{169}\\\\x=9.5\%](https://tex.z-dn.net/?f=16%3Ax%3D169%3A100%5C%25%5C%5C%5C%5C169x%3D16%5Ccdot%20100%5C%5C%5C%5C169x%3D1600%5C%5C%5C%5Cx%3D%5Cfrac%7B1600%7D%7B169%7D%5C%5C%5C%5Cx%3D9.5%5C%25)
So we get that 9.5% of women smoke.
We get: 13.9%-9.5%=4.4%.
So, we conclude that the best estimate for the difference in the proportion of smokers is 4.4%.
