Answer:
(0.5446, 0.6554)
Step-by-step explanation:
As the sample is sufficiently large, the formula is used to estimate the proportion shown in the attached image.
Where:
P: sample proportion = 0.6
n: Sample size = 300
: Confidence level = 0.95
α: Significance = 0.05
*
* Obtained from the normal standard table.
When introducing these values in the formula shown in the image we obtain:


Finally, the confidence interval is:
(0.5446, 0.6554)
