WebFirst let’s start with the meaning of a two-tailed test. If you are using a significance level of 0.05, a two-tailed test allots half of your alpha to testing the statistical significance in one direction and half of your alpha to testing statistical significance in the other direction.

WebSolve. Example 1 • Example 2. The first step in hypothesis testing is to calculate the test statistic. The formula for the test statistic depends on whether the population standard deviation (σ) is known or unknown. If σ is known, our hypothesis test is known as a z test and we use the z distribution. If σ is unknown, our hypothesis test ... WebFor a right-tailed hypothesis test at the significance level α, the null hypothesis H 0 : μ = μ 0 will be rejected in favor of the alternative hypothesis H a : μ > μ 0 if and only if μ 0 is less than or equal to the ( 1 − α)-level lower confidence bound for μ.Illustrate the preceding relationship by obtaining the appropriate one-sided one-mean z-interval for the data below.
