WebMar 17, 2024 · We use the Z-test for proportions when your sample size is greater than or equal to 30 (n \geq ≥ 30), and the distribution of the sample statistic is assumed to be normal. The formula for the Z-test statistic for population proportions is: Z =\frac {\hat {p}-p_ {0}} {\sqrt\frac {p_ {0} (1-p_ {0})} {n}} Z = np0(1−p0)p^−p0 WebThe value you originate from your statistics is known as the F-value or F-Statistic. The F-critical value is a specific value to which your F-value is compared. You can reject the null hypothesis if your calculated F-value in a test is greater than your F-critical value. In an F-Test, however, the statistic is only one measure of significance.
