4.164 
Suppose a random sample of n = 25 measurements is selected from a population with mean μ and standard deviation σ. For each of the following values of μ and σ, give the values of μ_{xÌ„} and σ_{xÌ„}.

Calculate standard error of mean and make an inference about the accuracy of the mean by analyzing problem 4.164 listed above.
Problem 2: Associated Probability
Resources: Table IV in Appendix B of Statistics for Business and Economics. See attachment, pgs 910.
Demonstrate how to find the area under the normal curve.
Determine the associated probability with zscore = 1.96.
Open Table IV Under Curve areas and find .475.
Find the same information by working the problem backwards, starting with the alpha (significance level).
