A sample of 26 offshore oil workers took part in a simulated escape exercise, resulting in the accompanying data on time (sec) to complete the escape. Here is a stem-and-leaf display of escape time data. (View Pic Below) (a) Determine the value of the fourth spread. (b) Are there any outliers in the sample? Any extreme outliers? There are no extreme outliers but several outliers. There is one extreme outlier and several outliers. There are no outliers or extreme outliers. There are several extreme outliers. There is one extreme outlier and one outlier. (c) Construct a boxplot. Comment on its features. The distribution is roughly symmetric with several outliers. The distribution is positively skewed with several outliers. The distribution is roughly bimodal with no outliers. The distribution is roughly symmetric with no outliers. The distribution is negatively skewed with several outliers. (d) By how much could the largest observation, currently 423, be decreased without affecting the value of the fourth spread? ? sec
