You can put this solution on YOUR website! Note: You have asked several of these questions.
Are you learning anything from the answers provided?
------------------------------------------------------
Given a level of confidence of 99% and a population standard deviation of 13, answer the following:
n = [z*s/E]^2
The 99% determines "z"
std = 13 determines "s"
=======================================
(A) What other information is necessary to find the sample size (n)?
You need E---the margin of error
--------------------------------------
(B) Find the Maximum Error of Estimate (E) if n = 61.
61 = [2.3263*13/E]^2
-----
2.3263*13/E = sqrt(61)
----
E = 2.3263/sqrt(61)
E = 0.2979
===============
