You wish to test the following claim (HaHa) at a significance level of α=0.10α=0.10. Ho:p1=p2Ho:p1=p2 Ha:p1≠p2Ha:p1≠p2 You obtain 131 successes in a sample of size n1=225n1=225 from the first population. You obtain 488 successes in a sample of size n2=769n2=769 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. 1. What is the z-score of the critical value? (Report answer accurate to three decimal places.) ±± 2. What is the standardized test statistic for this sample? (Report answer accurate to three decimal places.) 3. The test statistic is... A.) in the critical region B.) not in the critical region
