A political interest group wants to determine what fraction p ∈ (0, 1) of the population intends to vote for candidate A in the

mash [69]

Answer:

95% confidence interval for the true fraction p is (0.426, 0.488)

Step-by-step explanation:

Confidence Interval can be calculated using p±ME where

p is the sample proportion ( $\frac{457}{1000} =0.457$

ME is the margin of error from the mean

and margin of error (ME) around the mean can be found using the formula

ME= $\frac{z*\sqrt{p*(1-p)}}{\sqrt{N} }$ where

z is the corresponding statistic in 95% confidence level (1.96)
p is the sample proportion (0.457)

N is the sample size (1000)

then ME= $\frac{1.96*\sqrt{0.457*0.543}}{\sqrt{1000} }$ ≈ 0.031

Then 95% confidence interval would be 0.457±0.031 or (0.426, 0.488)
