Q1: A test equal to (first average mean) with (average of other treatment averages) using a method

Contrasts :

Defining hypotheses: null hypothesis and alternative hypothesis

Calculating the value of the test statistic

• Finding critical (tabular) values

• Determine the area of rejection and acceptance of the null hypothesis

• the decision

Conclusion

i want answers  by R or spss or by hand or what you Preferred

Answer 1

Following is the R script to run ANOVA:

----------------------------------------------

Following is the output:

The critical value of F is 3.239.

Rejection region:

if F > 3.239 reject H0

Decision: Reject H0

Conclusion: The averages for all four treatments are not same.
