In testing H0: p1 - p2 <= 0 versus Ha: p1 - p2 > 0 where p1 and p2 denote the two population proportions, the value of the test statistic is found to be z = 1.82. Then, the P-value is .9312 .0688 .4656 .0344

Step 1
In this case, the null hypothesis (Ho) is that the product of the two population proportions (p1*p2) is less than 0. The alternative hypothesis (Ha) is that the product of the two population proportions is not less than 0. The test statistic (Z) is 1.82. This Show more…

When testing H0: p1 - p2 = 0, versus HA: p1 - p2 ≠ 0, the observed value of the Zc test statistic was found to be -2.13. The p-value for this test statistic is 0.0166.

For a test of population proportion H0: p = 0.50, the z test statistic equals 0.9. a) What is the p-value for Ha: p > 0.50? b) What is the p-value for Ha: p ≠ 0.50? c) What is the p-value for Ha: p < 0.50?

We are performing a one-tailed hypothesis test for the population mean μ using the following pair of hypotheses: H0: μ =14.0 vs. Ha: μ > 14.0 We will test at (alpha) α = 0.01. After analysing the data we calculate the test statistic z = 2.108. What is the P-value for the test? Calculate the P-value for the test, correct to 3 decimal places
