A) F(2,15) = 3.80, p < .05
B) F(2,15) = 3.80, p > .05
C) F(2,18) = 3.80, p < .05
D) F(3,18) = 3.80, p < .05

Final Answer : A, Explanation :  The correct way to present the analysis is F(2,15) = 3.80, p < .05. The degrees of freedom for the numerator is the number of groups minus one (3 groups - 1 = 2), and for the denominator, it's the total number of subjects minus the number of groups (18 subjects - 3 groups = 15). The p-value indicates whether the result is statistically significant, with p < .05 typically considered significant.
