Use the degrees of confidence and a sample data to construct a 95% confidence interval for the population proportion.
A survey of 200 union members in New York reveals that 112 favor the republican candidate for governor.
From the given information,
n=200
p^= 112/200 = 0.56
Hence,
By using confidence interval calculator,
The required 95% confidence interval is,
(0.4912,0.6288)
Thank you.
