Hello, I am doing the Practical Case myself along with the video. Can you explain why you did not include the shoe size 11 and 12 in the women shoe frequency distribution table? These size have a frequency for women of respectively 45 and 78. Thank you,

Hi Lisa, I checked the solution file and I believe they were included there. Please take a look and let me know if the issue hasn't been solved. Best, Ned

Thank you for your answer Ned. They are not included in the video and attached lesson excel file but you are right they are in the exercise files. I understand it is not easy to amend the video. When I did the exercice myself I wondered if it was a mistake on my part, so maybe it could be corrected in the lesson file https://learn.365datascience.com/courses/statistics/practical-example-confidence-intervals
