1. Radish seedlings were randomly distributed and then grown under four conditions: natural lighting, darkness, regular (incandescent) light bulb, and full spectrum light bulb (providing ultraviolet lighting). Heights of the seedlings were measured after 9 days. Mean and standard deviations for radish heights for each of the four groups with sample sizes 20, 25, 20 and 24 were calculated for an ANOVA. The Between Sum of Squares and Within Sum of Squares were found to be 665.66 and 695.97. What would be an appropriate null hypothesis?
 
A. The mean radish seedlings in the four given conditions are equal.
 
B. The four given mean radish seedlings are equal.
 
C. The mean seedling heights in the four given conditions are equal.
 
D. The four given mean conditions are equal.
 
2. What would be the computed F statistic?
 
A. 26.733
 
B. 0.944
 
C. 0.033
 
D. None of these
 
3. What is the degree of freedom of the corresponding F distribution?
 
A. (3, 85)
 
B. (4, 85)
 
C. (3, 89)
 
D. (4, 89)
