96% confidence interval for the fraction of the voting population favoring the suit is [0.498 , 0.642].
Step-by-step explanation:
We are given that a random sample of 200 voters in a town is selected, and 114 are found to support an annexation suit.
Firstly, the pivotal quantity for 96% confidence interval for the fraction of the voting population favoring the suit is given by;
P.Q. = ~ N(0,1)
where, = proportion of voters found to support an annexation suit in a sample of 200 voters = = 0.57
n = sample of voters = 200
p = population proportion
Here for constructing 96% confidence interval we have used One-sample z proportion statistics.
So, 96% confidence interval for the population proportion, p is ;
P(-2.0537 < N(0,1) < 2.0537) = 0.96 {As the critical value of z at 2%
significance level are -2.0537 & 2.0537}
P(-2.0537 < < 2.0537) = 0.96
P( < < ) = 0.96
P( < p < ) = 0.96
96% confidence interval for p =[ , ]
= [ , ]
= [0.498 , 0.642]
Therefore, 96% confidence interval for the fraction of the voting population favoring the suit is [0.498 , 0.642].
