You read about a survey in a newspaper and find that 70% of the 250 people sampled prefer candidate a. you are surprised by this survey because you thought that more like 50% of the population preferred this candidate. based on this sample, is 50% a possible population proportion?

50% is not a possible population proportion who support candidate A.

Step-by-step explanation:

I will estimate 95% confidence interval to see if 50% a possible population proportion who support candidate A.

95% Confidence Interval can be calculated using  

CI=p± where

Then CI=0.70±≈ 0.70±0.06

That is 95% confidence interval is (64%, 76%). Since 50% is less than lower CI limit, 50% is not a possible population proportion who support candidate A.
