Answer :
Final answer:
In a poll of 150 voters, with 78 supporting the incumbent candidate, the proportion supporting the incumbent is 0.52 or 52%.
Explanation:
In the context of the political poll given, the proportion of voters supporting the incumbent candidate can be determined by dividing the number of voters who plan to vote for the incumbent by the total number of voters polled. In this case, 78 voters plan to vote for the incumbent candidate out of a total of 150 randomly selected voters.
To find the proportion, the calculation is as follows: Proportion = Number supporting incumbent / Total number polled = 78 / 150. This results in a proportion of 0.52, or 52%, when expressed as a percentage.
This kind of statistical analysis is commonly used in political polls to estimate popular support for candidates, issues, or beliefs.
