Question

You wish to test the following hypotheses at a significance level of α = 0.002 . H 0 : p 1 = p 2 H A : p 1 ≠ p 2 You obtain a sample from the first population with 48 successes and 239 failures. You obtain a sample from the second population with 107 successes and 340 failures. Suppose that all assumptions are met, so that the difference in sample proportions follows a normal distribution. What is the test statistic for this sample? (Report answer accurate to two decimal places.) z =

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) α greater than α=
