Chapter 3.4, Problem 51E
Annual sales, in millions of dollars, for 21 pharmaceutical companies follow.
- a. Provide a five-number summary.
- b. Compute the lower and upper limits.
- c. Do the data contain any outliers?
- d. Johnson & Johnson’s sales are the largest on the list at $14,138 million. Suppose a data entry error (a transposition) had been made and the sales had been entered as $41,138 million. Would the method of detecting outliers in part (c) identify this problem and allow for correction of the data entry error?
- e. Show a boxplot.
