At a sawmill in Victoria, a process improvement team measured the diameters for a sample of 1,200 logs. The following summary statistics were computed:

Q1 = 8.9cm

Q2 = 13.5cm

Q3 = 15.6cm

x-bar = 12.2cm

Given this information, which of the following statements is correct?

Group of answer choices

A log that is over 20cm in diameter can be considered an outlier

The distribution of log diameters is left-skewed

The distribution of log diameters is symmetric

The distribution of log diameters is right-skewed
