Question

lo estimate the percentage of a state's voters who supportthe current governor for reelection, three newspapers eachsurvey a simple random sample of voters. Each papercalculates the percentage of voters in its sample who supportthe governor and uses that as an estimate for the populationparameter. Here are the results:• The Tribune: n= 900 voters sampled; sample estimate =73%• The Herald: n= 700 voters sampled; sample estimate =69%• The Times: n= 500 voters sampled; sample estimate =83%All else being equal, which newspaper's estimate is likely tobe closest to the actual percentage of voters who support thegovernor for reelection?

Answer 1

Step-by-step explanation

The surveys performed by the newspapers were made to estimate the proportion of voters that will vote for the current governor.

The only way to find the proportion of voters with absolute precision is to survey all the voters. Since surveying all the voters is costly small surveys are performed instead. The closer size of the survey is to the actual number of voters the more accurate its results are.

Following this deduction the best estimation is the one calculated from the largest survey i.e. the one from The Tribune.

Answer

Then the answer is option A, The Tribune.
