<u>Answer-</u>
A 95% confidence interval for the true percent of movie goers is 36.41% to 44.25%
<u>Solution-</u>
Given,
n = 600 (sample size)
x = 252 (number of people who bought)
Confidence interval = 95%, so z = 1.96
We know that,

where,
M = sample mean
Z = Z statistic determined by confidence level
SE = standard error of mean
Calculating the values,

from the tables


Putting all the values in the formula,





Answer:
0.17155425219941%
Step-by-step explanation:
100%/x%=682/1.17
(100/x)*x=(682/1.17)*x - we multiply both sides of the equation by x
100=582.90598290598*x - we divide both sides of the equation by (582.90598290598) to get x
100/582.90598290598=x
0.17155425219941=x
x=0.17155425219941
