A researcher was interested in stress levels of lecturers during lectures. She took the same group of eight lecturers and measured their anxiety (out of 15) during a normal lecture and again in a lecture in which she had paid students to be disruptive and misbehave. Based on the SPSS output, how would you interpret these results?
A) Anxiety levels were significantly lower in lectures in which students misbehaved.
B) There were no significant differences between anxiety levels in normal lectures and in those in which students misbehaved.
C) Anxiety levels were significantly higher in lectures in which students misbehaved.
D) We can't tell any of the above from the output given.

The output shows that the mean anxiety level for normal lectures was 6.375 and the mean anxiety level for lectures where students misbehaved was 11.5. The p-value of 0.000 indicates that there is a significant difference between these two means, with anxiety levels being significantly higher in the disrupted lectures. Therefore, choice C is the correct answer.
