Explanation / Answer

Question a ) Option a

Question b) IQR = Q3 - Q1 = 528.3 - 273.8 = 254.5

Interpretation of IQR = Option a

Question c) Lower fence =Q1 - 1.5*IQR = 273.8-1.5*254.5 = -107.95

Upper fence =Q3 + 1.5*IQR = 528.3 + 1.5*254.5= 910.05

1679 is an outlier since ita greater than upper fence - Option a

Question d) Option a
