<PRE><B>Question 441918</B>
A report states that 44% of home owners have a vegetable garden. How large a sample is needed to estimate the true proportion of home owners who have vegetable gardens to within 4 percentage with 92% confidence? 
------
Since E = z*sqrt(pq/n)
---
n = [z/E}^2*(pq)
-----
n = [1.7507/0.04]^2(0.44*0.56)
---
n = 472 when rounded up
