You wish to test the following claim (Ha) at a significance level of a = 0.10. Ho: P1 = P2 Ha: P1 P2 You obtain 60 successes in a sample of size n₁ = 680 from the first population. You obtain 65 successes in a sample of size n₂ = 473 from the second population. What is the test statistic for this sample? (Report answer accurate to three decimal places.) test statistic = -2.643 x o What is the p-value for this sample? (Report answer accurate to four decimal places.) p-value 0.04 x
You wish to test the following claim (H) at a significance level of a 0.005. H. = Pz Ha:Pi Pr You obtain 93.5% successes in a sample of size n = 566 from the first population. You obtain 95.1% successes in a sample of size n₂ = 650 from the second population. What is the test statistic for this sample? (Report answer accurate to three decimal places.) test statistic- 0.904 x What is the p-value for this sample? (Report answer accurate to four decimal places.) p-value= The p-value is... O less than (or equal to) a M Ogreater than a This test statistic leads to a decision to... O reject the null O accept the null O fail to reject the null As such, the final conclusion is that... O There is enough evidence to support that the first population proportion is not equal to the second population proprtion. O There is not enough evidence to support that the first population proportion is not equal to the second population proprtion. There is enough evidence to reject that the first population proportion is not equal to the second population proprtion. O There is not enough evidence to reject that the first population proportion is not equal to the second population proprtion.
