Question
You wish to test the following claim (Ha) at a significance level of a = 0.05. H.:P1 = P2 Ha:P1 < P2 You obtain 45.2% successes in a sample of size ny = 239 from the first population. You obtain 54% successes in a sample of size n2 = 766 from the second population. 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... O less than (or equal to) a O greater 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 sufficient evidence to warrant rejection of the claim that the first population proportion is less than the second population proportion. O There is not sufficient evidence to warrant rejection of the claim that the first population proportion is less than the second population proportion. O The sample data support the claim that the first population proportion is less than the second population proportion. O There is not sufficient sample evidence to support the claim that the first population proportion is less than the second population proportion.
