A climatologist measures daily rainfall amounts (mm) for $11$ days: $0.5,0.8,1.0,1.2,1.3,1.5,1.6,1.8,2.0,2.1,2.4$. Use the boxplot/ quartile method to evaluate whether the distribution of these rainfall amounts is symmetric. Which conclusion is correct?

Approximately symmetric because $Q_1=1.0,Q_2=1.5,Q_3=1.8,IQR=0.8$ and fences exclude $2.4$ as an outlier.

Right-skewed because $Q_1=1.0,Q_2=1.6,Q_3=1.9,IQR=0.9$ and upper whisker is much longer.

Approximately symmetric because $Q_1=1.0,Q_2=1.5,Q_3=2.0,IQR=1.0$ and distances to median are similar

Left-skewed because $Q_1=1.2,Q_2=1.5,Q_3=1.8,IQR=0.6$ and lower whisker is longer.
