Keep in mind, however, that because of the central limit theorem, the one-mean z-test will work reasonably well when the sample size is large, regardlessof the distribution of the variable example: Determine the critical value(s) for a one-mean z-test at the 5% significance level(α = 0.05) if the test is 一般的: ...

In the following tutorials, we demonstrate the procedure of hypothesis testing in R first with the intuitive critical value approach. Then we discuss the popular p-value approach as alternative. Lower Tail Test of Population Mean with Known Variance ...
For the critical value approach we need to find the critical value (CV) of the significance level (α).For a population proportion test, the critical value (CV) is a Z-value from a standard normal distribution.This critical Z-value (CV) defines the rejection region for the test....
It is also possible to determine the critical value of the test and use to calculated test statistic to determine the results. Either way, using the p-value approach orcritical valueshould provide the same result. Create a Visual Aid of the Test ...
Undercritical value approach, the decision rule will be as follows: Reject the null hypothesis iftest-statistic < -1.28 If the test statistic is -1.46, we will reject the null hypothesis. We can calculate the p-value as follows: We will look for the value of F(Z) whereZ=-1.46. This...
Method 1: Critical Value Approach Identify a critical value XLfor the sample mean, which is large enough to reject the null hypothesis – i.e. reject the null hypothesis if the sample mean >= critical value XL P (identify a Type I alpha error) = P (reject H0given that H0is true), ...
Briefly compare and contrast the critical values approach and the p-value approach for determining the statistical significance of a hypothesis test. If the p-value approach to hypothesis testing is used, the decision is based on: a. comparing the p-value to ...
What is the six-step critical value approach to hypothesis testing? Determine whether the claim stated below represents the null hypothesis or the alternative hypothesis. If a hypothesis test is performed, how should you interpret a decision that (a) rejects ...
