WebA test of H0: p = 0.4 versus Ha: p > 0.4 has the test statistic z = 2.52. Part A: What conclusion can you draw at the 5% significance level? At the 1% significance level? Part B: … Web16 Jul 2024 · The p value gets smaller as the test statistic calculated from your data gets further away from the range of test statistics predicted by the null hypothesis. The p value is a proportion: if your p value is 0.05, that means that 5% of the time you would see a test statistic at least as extreme as the one you found if the null hypothesis was true.

Web21 Apr 2010 · In a test of H0: p = 0.4 against Ha: p 0.4, a sample of size 100 produces z = 1.28 for the value of the test statistic. Thus the P-value (or observed level of significance) of the test is approximately equal to: I wanna this is .90 because of the z=1.28 but it seems wrong to completely disregard the other givens. 1. Some scientists believe that ... WebIn our Z-test calculator, you can decide whether to use the p-value or critical regions approach. In the latter case, set the significance level, α \alpha α.

A test of significance was conducted on these hypotheses: Ho: The survival rates for the two treatments are equal. Ha: Treatment 2 produces a higher survival rate. The statistical test resulted in a p-value of o.0018.
