Thank you! Your videos are really helpful ❤️
You're so welcome! If you like our video lessons, it would be appreciated if you could take 2 minutes of your time to leave us a Google review using this link: g.page/r/CQIlM78xSg01EB0/review
@ around 11:40, when finding the t value, why is the degree of freedom 28? the sample has 30 observations, and n-1 so i thought the degree of freedom is 29?
Because we are estimating two parameters (B0 and B1) so the degrees of freedom are calculated as n - 2 so 28. It's written in the slide in minute 7:40 :)
@19:16 You mean it that it will no long be efficient. You said "It is no longer going to be inefficient" twice.
You are correct. Sorry about that. We meant "not efficient" as it is written on the slide.
