  1. The partially completed table and partially completed histogram give information about the ages of passengers on an airline.
There were no passengers aged 90 or over.
Age ( \(x\) years)\(0 \leqslant x < 5\)\(5 \leqslant x < 20\)\(20 \leqslant x < 40\)\(40 \leqslant x < 65\)\(65 \leqslant x < 80\)\(80 \leqslant x < 90\)

  1. Complete the histogram.
  2. Use linear interpolation to estimate the median age. An outlier is defined as a value greater than \(Q _ { 3 } + 1.5 \times\) interquartile range.
    Given that \(Q _ { 1 } = 27.3\) and \(Q _ { 3 } = 58.9\)
  3. determine, giving a reason, whether or not the oldest passenger could be considered as an outlier.
