You wish to test the following claim (HaHa) at a significance level of α=0.002α=0.002. Ho:p1=p2Ho:p1=p2 Ha:p1≠p2Ha:p1≠p2 You obtain 480 successes in a sample of size n1=647n1=647 from the first population. You obtain 562 successes in a sample of size n2=737n2=737 from 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 answer accurate to three decimal places.) ±± What is the standardized test statistic for this sample? (Report answer accurate to three decimal places.) The test statistic is... in the critical region not in the critical region This test statistic leads to a decision to... reject the null accept the null fail to reject the null

What is the standardized test statistic for this sample? (Report answer accurate to three decimal places.)
The test statistic is...
- in the critical region
- not in the critical region
This test statistic leads to a decision to...
- reject the null
