Homework Answers

Answer #1

The minimum sample size (n) is given by:

Since Significance Level = is not provided, Take the usual value of = 0.05

For = 0.05, critical values of Z = 1.96

Since p is not provided, Take the usual value of p = 0.5

Given :

e = 0.013

Substituting, we get:

So,

Answer is:
