Very good explanation thank you! That being said, I might have picked up a tiny mistake in the code. Indeed, should it not be "observed_z_score = blabla / sample_sd" instead of "observed_z_score = blabla / sigma" since the sigma variable is part of what we are not supposed to know (population standard deviation)? If I am right, this must have completely thrown off the z score calculation.
Thanks for the video Emma, it's really handy! Just a suggestion - Might be useful to also share an example of a one-tailed test (for example when we want to test if the population mean is greater than or lesser than a target value).
Thank you for your thoughtful feedback, Abhinav! I appreciate you taking the time to share that with me. I will take it into consideration for future videos. 😊
Many of you have asked me to share my presentation notes, and now… I have them for you! Download all the PDFs of my Notion pages at www.emmading.com/get-all-my-free-resources. Enjoy!

The presentation is super helpful and clear! Thanks Emma! Could you please share the notes?

The best part is you add coding with the theory and explained quite well!
Thanks, Allie! So glad you found it helpful! Thanks for watching. 💛
