Confidence interval: 99%

Hello,   Lecture 58 (see at 6:20).   When choosing the confidence interval of 99%, hence an alpha of 1%, can you please explain why did you choose the value 0.9951 and not 0.9949?   Both of these are equidistant to 0.995, and therefore, I was wondering if there was a general rule when rounding it or if this was just arbitrary.   I look forward to hearing from you,   Kind regards, Jake

Hello, Jake Lang!   That was arbitrary.   Either way, the result would be the same. 0.9951 is a bit (like a reeeally tiny bit) stricter than 0.9949.   If you are using software, then you would get the exact value: 0.995, instead of dealing with the table!   Best,
