Example: Compare four fertilizers used in four fieldsH0: The average weight of crops per square meter is equal in all fields.H1: At least one field yields a different average per square meter. Right-tailed, for ANOVA test you can use only the right tail. Why? Hypotheses H0:μ1 = ......

Just look at the estimated effect. In the output below, the t-value is negative, so we know that the test statistic fell in the critical region in the left tail of the distribution, indicating the mean is less than the target value. Now we know this difference is statistically significant...
Meaning be 95% sure (respectively 99%) that the lower limit of voter proportion is higher than 53 – z for 95% one-tail normal distribution (99% one-tail, respectively)? Or this is incorrect to be done? Thank you, Cristian, Example 2 does use a 1-tailed test. ...
Real Statistics Functions: The following functions are provided in the Real Statistics Pack: RLowerCRIT(n1, n2,α, tails) = lower-tail critical value of the runs test for a sample withn1 elements of one type andn2 elements of the other type, whereαis the significance level (default .05...

The Left-tailed test is also known as a Lower-tail test. A hypothesis test is performed if the population parameter is suspected to be less than the assumed parameter of the Null Hypothesis. H0: μ≥μ0 H1: μ<μ0 Example of a One-Sample T Hypothesis Test in a DMAIC Project ...
While no single score is best in all cases, some scores excel in specific contexts. In addition to predictive accuracy, the study also evaluates computational efficiency and identifies scores that are suitable for resource-constrained scenarios. This research provides insights for selecting appropriate ...
