Question
![**Survey on Left-Handed Golfers**
In a survey of 2,490 golfers, 22% said they were left-handed. The survey's margin of error was 4%. Construct a confidence interval for the proportion of left-handed golfers.
### Provided Options
- (0.17, 0.27) [Selected Option]
- (0.18, 0.26)
- (0.18, 0.22)
- (0.26, 0.30)
### Explanation:
In this question, the goal is to construct a confidence interval based on the given proportion and margin of error. The selected option indicates that the constructed confidence interval for the proportion of left-handed golfers is (0.17, 0.27).
This means that the survey estimates with 95% confidence that the true proportion of left-handed golfers lies between 17% and 27%.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F08ad6c20-d691-4a3f-8949-0fe4518b5718%2Ff3d3b5bb-c9a7-4faa-add4-cb6ae2d5ae19%2F6tnl6l6_processed.jpeg&w=3840&q=75)
