Minor typo in Lesson 22 #17

Open khangquangtran opened 2 years ago

khangquangtran commented 2 years ago

In the Lesson 22, near the beginning:

In other words, our model is mean weight = β0 + β1 height where β0 and β1 are the intercept and slope of the population regression line.

Isn't it beta_1 weight, instead of beta_1 height?

This one was correct, but thanks so much for the others!

I'm sorry, I'm new to statistics, so I am probably wrong about linear regression. Please correct me if I understand wrong.

The model is about the weight and the age, isn't it? Or is it about the weight and the height? From the last code section of Lesson 21 and the first code section of Lesson 22, I think that the model is about the weight and the age.
