Abook sold 33,700 copies in its first month of release.
suppose this represents 9.2% of the number of copies sold to date.
how many copies have been sold to date?

What is the correlation coefficient for the data? don't forget to turn the diagnoisticon (in the catalog menu of the calculator). r = answer (round to the nearest thousandth)

Can someone answer this question? : )
