Answer 1

In Moreno County,

Proportion of households in Lemonville $= \frac{400}{400+1000+1500} = \frac{400}{2900} = 0.137 \approx 0.14 =14\%$

Proportion of households in Havenford $= \frac{1000}{400+1000+1500} = \frac{1000}{2900} = 0.345 \approx 0.35=35\%$

and

Proportion of households in Charlotteville $= \frac{1500}{400+1000+1500} = \frac{1500}{2900} = 0.51 =51\%$

The sampling method that is most appropriate for this study : stratified random sampling

ans-> The researcher should gather 14% of the surveys from Lemonville, 35% from Havenford and 51% from Charlotteville.
