As we find errors, we'll list them on this page by chapter. If there is an error in a solution file for some problem, we will try to indicate a way to fix the error without "giving away" the solution to students who might be reading this page.
Note: The date of the correction is listed.

(7/26/2018) Problem 31 is missing an x in the fourth term of the Yield. It should be x-sub 1 squared.
(8/1/2018) Close inspection of the chart in the solution to problem 6 shows that it doesn’t graph the rows of the data table correctly. This is evidently because of a link to the example file. To correct the problem, select Edit Links on the Data ribbon and then break the link.

(10/8/2018) The reference to row 37 in the second line of page 297 should be changed to row 8.
Chapter 7
(10/2/2020) It’s not a mistake, but for a more interesting sensitivity analysis on problem 7_52, let the capacity vary from 500 to 700 in increments of 25.
Chapter 8
(11/23/2017) The statement about unused capacity in the next-to-last line on page 427 isn’t quite correct. Only compartment 4 has unused capacity.
(11/23/2017) In Example 8.4, you might take issue with the way model changeovers are handled, as described in the first bullet on page 430. This is probably a fault of our “changeover” terminology. Our meaning is that there is a penalty in any week for each model that is produced at a positive level – regardless of whether that model was produced at a positive level in the previous week.
Chapter 9
(12/8/2020) The problem file, P09_59.xlsx, and the solution file, S09_59.xlsx, don’t match the statement of problem 9.59 on page 506. Unlike other problems (and the chapter example) that require Bayes’ rule, they list actuals along the top and indications along the side. The easiest fix is to reverse these, as in the revised file P09_59.xlsx, and make the corresponding changes in rows 14-18 of the S09_59.xlsx solution file. After making this change, the solution file is correct; the result is exactly the same.

(11/22/2017) In the fourth line from the bottom on page 771, the salary mentioned should be $125,000, not $1,25,000.
(11/22/2017) The left side of the third formula on page 775 should be ln (p…, not In a (p… . That is, it should be the natural logarithm of p/(1-p).
(11/22/2017) The eighth line from the bottom on page 788 should read Mall Trips, not Mall Values.
(11/22/2017) The second line of step 2 on page 798 should refer to Figure 14.25, not 8.31, the seventh line of step 4 on page 798 should refer to Figure 14.26, not 8.32, the second line on page 799 should refer to Figure 14.25, not 8.31, and the third line of step 6 on page 799 should refer to Figure 14.25, not 8.31. (Sorry, this example was taken from Chapter 8 of our Data Analysis book, and we forgot to change the figure references.)
