Question
A sample of 20 glass bottles of a particular type was
selected, and the internal pressure strength of each bottle
was determined. Consider the following partial sample
information:
median 5 202.2 lower fourth 5 196.0
upper fourth 5 216.8
Three smallest observations 125.8 188.1 193.7
Three largest observations 221.3 230.5 250.2
a. Are there any outliers in the sample? Any extreme
outliers?
b. Construct a boxplot that shows outliers, and comment
on any interesting features.
