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.
