1) 3 and 30

2) 4 and 30

3) 3 and 119

4) 3 and 116

5) None of the above answers is correct

2) describe which of the following is not a required assumption for the analysis of variance?

1) The random variable of interest for each population has a normal distribution

2) The variance associated with the random variable must be the same for each population

3) At least 3 populations are under consideration

4)  All of the above are required assumptions

3) describe - In analysis of variance one estimate of 2 is based upon the differences between the treatment mean and the

1) means of each sample

2) overall sample mean (grand mean)

3) sum of observations

4) describe the critical value with 6 numerator and 60 denominator degrees of freedom at  =0.05 is

1) 3.74

2) 2.37

3) 2.45

4) None of the above is the correct answers

5)  describe a variable of interest in an ANOVA procedure is called

1) a partition

2) a treatment

3) either a or b

4) a factor

5) None of the above is the correct answer.

6) Describe In factorial designs, the response produced when the treatments of one factor interact with treatments of another in influencing the response variable is

1) main effect

2) replication

3) interaction

4) None of the above answers is correct

7) describe an experimental design where the experimental units are randomly assigned to the treatments is known as

1) factor block design

2) random factor design

3) completely randomized design

4) None of the above answers is correct

8) Whenever we have more than one factor influencing the response and we want to investigate the influence of all factors on the response then we should be conducting

1) Completely randomized design test

2) Randomized block test

3) Factorial experiment design test

4) None of the above answers is correct.
