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 = ......
The =TINV(probability, deg_freedom) is a function available in Excel that can be used to compute the critical t value for the given specification. The... Learn more about this topic: T-Test | Chart, Formula & Examples from Chapter 22/ Lesson 5 ...
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. Charles R...

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 ...
如pf(5,1,99,lower.tail=F) 组间样本显著性对比 ANOVA可以告诉我们组间样本平均值是否存在显著差异,但无法告诉我们差异是什么、在哪里。为了明确哪个或哪几个组具有更显著的差异,我们可以做Tukey's Honestly Significant Difference (Tukey's HSD) post-hoc test来进行成对分析。
