The following solution is suggested to handle the subject “Use the given degree of confidence and sample data to construct a confidence interval for the…“. Let’s keep an eye on the content below!
Question “Use the given degree of confidence and sample data to construct a confidence interval for the…”
Use the given degree of confidence and sample data to
construct a confidence interval for the population proportion
p.
construct a confidence interval for the population proportion
p.
n = 195, x = 162; 95% confidence
Answer
Solution:
Given
n = 195 sample size
X = 162
95% confidence interval for population percentage p
( 0.777280, 0.8827199)
( 0.7773, 0.8827)
95% confidence interval for population percentage p
( 0.7773, 0.8827)
162 p= = = 0.83307692 n.195
