The Null Hypothesis: Basics

Person 1 

I agree that the null hypothesis is wrong and hence reject the null hypothesis. After conducting my Anova analysis, I concur with your answer and that the p-value is greater than alpha. There is sufficient evidence which suggests that there is a disparity of means between the three groups. These questions have been answered adequately, and every step has been displayed, and therefore, it makes the work easier to follow each step and comprehend it ( List, Shaikh, & Xu, 2016) . The manner which the results conducted in Anova has been presented is intriguing since it is much easier to determine if the hypothesis is valid or void. 

From the table, pairwise confidence intervals include: 

Low vs. Medium ( 54.1 , 6.32222222 ) 

Low Vs. High ( 54.1 , 22.1 ) 

Medium vs. High (6.32222222, 22.1 ) 

Conclusion: Not all pairs contain 0; these imply these the pairwise had a significant difference, that concurs with the above conclusion based on the hypothesis conducted. 

Person 2 

The work displayed when answering the hypothesis is neatly arranged and display hence making it easier for individuals who have inadequate knowledge in Anova comprehend and follow the work with ease, and this is intriguing ( Park, 2015) . Basing on the table and result obtained I agree with you that the hypothesis can not be rejected as a null. There is adequate evidence that suggests the hypothesis is not null since, as the p-value is greater than alpha. 

From the table, pairwise confidence intervals include: 

Low vs. Medium (845.2381, 3573.81) 

Low Vs. High (845.2381, 10550) 

Medium vs. High (3573.81, 10550) 

Conclusion There are no pairs that contain 0; these imply these the pairwise had a significant difference, that concurs with the above conclusion based on the hypothesis conducted.
