A sample of 20 glass bottles of a particular type was selected, andthe internal pressure strength of each bottle was determined.Consider the following partial sample information:
median= 202.2
lower fourth= 196.0
upper fourth= 216.8

three smallest observation 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 anyinteresting features

Answer:

Yes, there is one outlier (lower)

Step-by-step explanation:

Looking at the distribution of the lower/smallest observation, we can see that there is a values in the lower/smallest that is very far from others. See the attached box-plot for understanding.

The median is the line in the middle of the box-plot.

The Lower fourth is the lower whisker line and upper fourth is the upper whisker line. The lower box  (just below the median) line is the 1st quartile and the upper box line (just above the median) is 3rd quartile.
