True or False
1. In a completely randomized experimental design with 10 treatments, if the sample size (n) is 40 and α = 0.05, then tukey’s critical value is qα = 4.82.
2. The Chi-Square distribution is a right-skewed distribution that is dependent on two degrees of freedom (the numerator df and the denominator df).
Solutions
Expert Solution
Solution:
1. In a completely randomized experimental design with 10 treatments, if the sample size (n) is 40 and α = 0.05, then Tukey's critical value is qα = 4.82.
Answer: This statement is TRUE.
The Tukey's critical value for k = 10 and dfw=n-k =
40-10 = 30 at 
is:
2. The Chi-Square distribution is a right-skewed distribution that is dependent on two degrees of freedom (the numerator df and the denominator df).
Answer: The statement is False.
The chi-square distribution depends on n - 1 degrees of freedom. There are no numerator df and denominator df in chi-square distribution.

A split-plot experiment was conducted in a completely randomized
design with whole-plot treatments as a 2x2 factorial (factors A and
B) and the subplot treatments as three levels of factor C. There
are four whole-plot replicants per whole plot treatment. Assume all
treatment effects were fixed and include all interactions between
factors.
Write the linear model for the experiment. Identify each of the
model effects/components and list the number of levels for each
effect. Make sure to specify which effects...
