A violin student records the number of hours she spends practicing during each of nine consecutive weeks: Considering the smallest data value (1.2) and using the 1.5 × IQR rule, we would:
A)classify the value 1.2 as an outlier, because it is more than 1.5 × IQR below the first quartile.
B)not classify the value 1.2 as an outlier, because it is not more than 1.5 × IQR below the first quartile.
C)classify the value 1.2 as an outlier, because it is more than 1.5 × IQR below the median.
D)classify the value 1.2 as an outlier, because it is more than 1.5 × IQR below the mean.
