I look at at what influences the choice of the t statistic or z statistic in one-sample hypothesis tests on the population mean mu, then work through an example of a t test. I compare the p-value of the t test to what we would have found had we (incorrectly) used a z test.

Would be cool if you made RStudio videos. Nevertheless, proper collection of videos so far. Thank you.

I’d like to make some R videos, but I’m working under some serious time constraints these days. I hope to get back to video production in the near future. Cheers.

You’ve saved my life with these videos – thank you so much!!!

You’re welcome! I’m glad I could be of help.
