Query for topics in week 22 and 23

What is the topic is covered in week 22 and 23

Rest of the topics are combined and will be released in Week 22, which will be the last checkpoint for the course.
Week 22 will cover Hypothesis Testing

What about ANOVA and Linear Regression? I see Week 23 too.

No, ANOVA and LR will not be covered for now, as the course is stretching more and more. They’ll probably be covered in some other course.
