Hypothesis Test for the Difference in Two Proportions You wish to test the following claim (Ha) at a significance level of a = 0.02. Ho: P1 = P2 Ha: P1 P2 You obtain 330 successes in a sample of size n₁ = 588 from the first population. You obtain 241 successes in a sample of size 7₂ = 405 from the second population. What is the test statistic for this sample? (Report answer accurate to three decimal places.) test statistic-0.787 X What is the p-value for this sample? (Report answer accurate to four decimal places.) p-value = 0.216 X The p-value is... O" less than (or equal to) a greater than a This test statistic leads to a decision to... O reject the null O accept the null fail to reject the null # 1
