Question

You wish to test the following claim (H) at a significance level of a = 0.02. H:P P2 HP1 + P2 You obtain a sample from the first population with 511 successes and 261 failures. You obtain a sample from the second population with 443 successes and 182 failures. 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 test statistic for this sample? (Report answer accurate to three decimal places.) test statistic - What is the p-value for this sample? (Report answer accurate to four decimal places.) P-value = The p-value is... less than or equal to) a Ogreater than a This test statistic leads to a decision to... Oreject the null O accept the null O fail to reject the null

Answer 1

p-value = 2P[221-1-951] = 0.0465 2o Decision : The p-value is greater than & ---- a decision to ... This test statistic leads to fail to reject the null. i istituttet ( 20
