Answer:
[ 0.4964, 0.5836 ]
Step-by-step explanation:
Data provided in the question:
Total sample size = 500
person voting for smith = 270
thus,
P( person voting for smith ), p =
= 0.54
Confidence level = 95%
now,
standard error, SE = ![\sqrt{\frac{p(1-p)}{n}](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cfrac%7Bp%281-p%29%7D%7Bn%7D)
or
SE = ![\sqrt{\frac{0.54(1-0.54)}{500}](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cfrac%7B0.54%281-0.54%29%7D%7B500%7D)
or
SE = 0.0223
now,
Confidence interval = p ± ( z × SE )
here,
z value for 95% confidence interval is 1.96
Confidence interval = [ 0.54 - ( 1.96 × 0.0223 ), 0.54 + ( 1.96 × 0.0223 ) ]
= [ 0.54 - 0.0436 , 0.54 + 0.0436 ]
= [ 0.4964, 0.5836 ]
