QUESTION 6 In the one-way ANOVA where k is the number of treatments and n is the number of observations in all samples, the degrees of freedom for treatments is given by: O a.k-1 Ob.n-K+1 Oc.n-1 O d.n-k

QUESTION 7 In ANOVA, the F-test is the ratio of two sample variances. In the one-way ANOVA (completely randomized design), the variance used as a numerator of the ratio is: O a.mean square for treatments. Ob.mean square for error. O c. total sum of squares. d. None of these choices.

QUESTION 8 In a completely randomized design for ANOVA, the numerator and denominator degrees of freedom are 4 and 25, respectively. The total number of observations must equal: O a. 24 O b.30 O c. 29 O d.25

QUESTION 9 The value of the test statistic in a completely randomized design for ANOVA IS F = 6.29. The degrees of freedom for the numerator and denominator are 5 and 10, respectively. Using an Ftable, the most accurate statements to be made about the p-value is that it is: O a. between 0.010 and 0.025. O b.greater than 0.05 O c. between 0.025 and 0.050. O d. between 0.001 and 0.010.

QUESTION 10 One-way ANOVA is applied to independent samples taken from four normally distributed populations with equal variances. If the null hypothesis is rejected, then we can infer that a. at least two population means are equal. O b.all population means differ. O c. at least two population means differ. O d. all population means are equal.
