Decide whether the normal sampling distribution can be used. If it can be used, test the claim about the difference between two population proportions p 1 and p 2 at the given level of significance alpha using the given sample statistics. Assume the sample statistics are from independent random samples.

Claim: p 1=p 2, a=0.10

Sample statistics: x 1=116, n 1=168 and x 2=98, n 2=182

1) Can normal sampling distribution be used?

2) Identify the null and alternative hypothesis.

3) Find the critical values

4) Find the standardized test statistic

5) State the conculusion
