NOTE: I AM SEEKING HELP WITH MICROSOFT EXCEL 2016.

For the textbook: Business Analytics: Data Analysis & Decision Making (6th Edition) by Albright and Winston - Question: chapter 8, problem 29 - I am trying to follow the instructions, however I believe the instructions provided are for an older version of Excel. I have Excel 2016 - can you please provide updated instructions for Excel 2016? I am able to follow through the pivot table but after that the Stattools instructions don't translate. I do not have a preference to use Stattools if there is another way to solve this problem. Please include any values that I can use along the way to check my work.

The question is as follows:

TABLE CREATED THROUGH PIVOT TABLE FUNCTION FROM THE DATA SET:

Count of Gender	Column Labels
Row Labels	F	M	Grand Total
Competing brand	90	26	116
Our brand	94	40	134
Grand Total	184	66	250

NOTE: THE ANSWER THAT CHEGG PROVIDES IS AS FOLLOWS: Lower Limit: -0.233, Upper Limit 0.043 . when I attempted to solve this problem the answers I produced are: Lower Limit: -0.043, Upper Limit 0.233 . In addition, I previously posted this problem and someone did the math with a paper and pen and got the same answer as me.... I wonder if it's possible that the answer posted on the Textbook's Chegg page is incorrect?

Of what value might this interval estimate be to marketing managers at the company
