You wish to test the following claim (Ha) at a significance level of α=0.002.      

Ho:p1=p2, Ha:p1≠p2 You obtain 344 successes in a sample of size n1=510 from the first population. You obtain 169 successes in a sample of size n2=216from the second population. For this test, you should NOT use the continuity correction, and you should use the normal distribution as an approximation for the binomial distribution.

What is the z-score of the critical value? (Report answers accurate to three decimal places.)

1. critical value

2. test statistic

3. accept or reject the null
