Critical value formula The formula of z and t critical value can be expressed as: Type of critical valuet critical value formulaz critical value formula Left-tailedQt,d(α)u(α) Right-tailedQt,d(1 - α)u(1 - α) Two-tailed±Qt,d(1 - α/2)±u(1 - α/2) ...
Z-critical Value Formula: The z-critical value can be calculated by the following formula left-tailed test: Φ-1(α); right-tailed test: Φ-1(1 − α); two-tailed test: ±Φ-1(1 - α/2) where Φ is the cumulative distribution function of the standard normal distribution. ...
The Z-score is 2.333. This value is greater than the critical value of 1.960, making the results statistically significant. Below is a graphical representation of our Z test results showing how the Z statistic falls within the critical region. We can reject the null and conclude that the mean...
