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: a.? re there any outliers in the sample? Any extreme outliers? b?. ?Construct a boxplot that shows outliers, and comment on any interesting features.
ANSWER:Solution: Step 1: Here a sample of 20 glass bottles of a particular type was selected. And the internal pressure strength of each bottle is noted. They also given the sample informations. Median=202.2 Three smallest observations = 125.8 188.1 193.7 Upper fourth(3rd quartile)= 216.8 Three largest observations = 221.3 230.5 250.2 Lower fourth(1st quartile) = 196.0 We have to construct a boxplot and want to find is there is any outliers in the Given data.
