Question 1197344: ou want to obtain a sample to estimate a population proportion. Based on previous evidence, you believe the population proportion is approximately 73%. You would like to be 90% confident that your estimate is within 4% of the true population proportion. How large of a sample size is required?
Hi
90% confident ⇒ z = 1.645,
p = .73, ME = .04
How large of a sample size is required?
n =
n = = 333.348 0r sample Size = 334
= CI z = value
90% z =1.645
92% z = 1.751
95% z = 1.96
98% z = 2.326
99% z = 2.576
Wish You the Best in your Studies.
