  10. 10Two classes of students took a music theory test. One class took the test at 9am and the other took the test at 11am. Professor Crescendo wants to compare the distribution of scores in each class. Professor Crescendo finds that the sum of squared deviations in her 9am class is smaller compared to her 11am class. Which of the following cannot be true of Professor Crescendo's two test distributions?
    1. AThe 9am class has the smaller standard deviation.
    2. BThe 11am class has the smaller variance.
    3. CThe 9am class has a standard deviation equal to the 11am class.
    4. DThe 9am class and 11am class have an equal number of student.
    5. EAll of these options are possibly true.
