An experiment was done to compare the effect of having a conversation via a hands-free mobile phone,having a conversation with an in-car passenger,and no distraction (baseline)on driving accuracy.Twenty participants from two different age groups (18-25 years and 26-40 years)took part.All participants in both age groups took part in all three conditions of the experiment (in counterbalanced order),and their driving accuracy was measured by a layperson who remained unaware of the experimental hypothesis. Which of the following sentences regarding the output below is correct? A)The output shows that the assumption of sphericity has been violated,$\chi$²(2)= 0.81,p = .17. B)The output shows that the assumption of sphericity has been violated,$\chi$² (2)= 3.58,p .05. C)The output shows that the assumption of sphericity has been met,$\chi$² (2)= 0.81,p .05. D)The output shows that the assumption of sphericity has been met,$\chi$²(2)= 3.58,p = .17.
