a. Import the Drinks.txt fi le from the
Chapter02 data folder into an Excel
workbook (note that columns are
delimited by tabs).
b. Create range names for each of the
fi ve data columns in the workbook.
c. Create two new columns displaying
the change in sales from 2000 to 2002
and the ratio of the 2000 sales to the
2002 sales. Assign range names to
these two new columns.
Sort the list in descending order of
the difference in sales.
d. Is there any relationship between the
year in which the brand was founded
and the change in sales? (Hint: Are
the older brands showing less growth
than the new brands?)
e. Repeat your analysis using the ratio of
sales.

f. Save the workbook in Excel format
to the Chapter02 folder under the
name Soft Drinks Sales Report and
write a report summarizing your
observations.


  1. The NCAA requires schools to submit
    information on graduation rates for its
    student athletes. Table 2-8 shows the
    data for the 11 schools in the Big Ten,
    covering the years 1997 through 2000,
    indicating the graduation percentage
    (within six years.) The overall gradua-
    tion percentage for all undergraduates
    is shown in the Graduated column and
    then is broken down by race and gender
    in the remaining four columns of the
    table for those who received athletic
    scholarships.
