To Find : Which statements about the data must be true
( ref attachment )
Solution:
Lower Quartile Q₁ = 4
Median = Q₂ = 7
Upper Quartile Q₃ = 9
Spread from lower Quartile to Median = 7 -4 = 3
Spread from Median to upper Quartile = 9 - 7 = 2
Spread from lower Quartile to Median > Spread from Median to upper Quartile
option 3 is correct
Option 1 is just opposite
Number of data values before median and above median are always Equal ( that what median is )
Hence option 2 and 4 are incorrect
