Web how to calculate the test statistic for the two samples? Use a z test when you need to compare group means. Then, we plug our known inputs (degrees of freedom, sample mean, standard deviation, and population mean) into the t distribution calculator and hit the calculate button. The z score test for two population proportions is used when you.

Two Sample ztest for Difference Between Means

The null hypothesis is usually that the means of the two samples are equal, while the alternative hypothesis is that the means are not equal. Μ1 ≠ μ2 (the two population means are not equal) we use the following formula to calculate the z test statistic: What is the continuity correction? Μ 1 = μ 2 (the two population means.
