Find the margin of error for the given values of c, σ, and n.
c=0.90, σ=3.3, n=81.
Eequals= _ (Round to three decimal places as needed.)
We know that :-
Margin of error = Critical value Standard error of the sample
Standard error of the sample = = = 0.3667
Critical value = Z/2
According to the problem : 1- = 0.90 =0.1 /2 = 0.05
Critical value = Z/2 = Z0.05 = 1.645
Margin of error = 1.645 0.3667 = 0.6031667
