Focus of today

For the past few lessons, we have learned the various components of a hypothesis test but today, we are finally ready to put together all the components and go through the procedure of conducting a hypothesis test from beginning to end.

There are various types of hypothesis tests. The simplest one is the “one-sample t test” in Ch 20, which is the focus of today.

Again, you can find the concepts in Ch 17 and the actual calculations in Ch 20.

Specifically,

— Ch 17 introduces concepts such as hypotheses, P-value and significance level, etc.

— Ch 20 shows how to use the t probability distributions to calculate a t test statistic and finding the corresponding P-value

 

Instructions

• There are 2 problems in this lab work. The problems are not in the book.

• • 1 hypothesis test problem (one-sided / one-sample t test)
  • 1 hypothesis test problem (two-sided / one-sample t test)

 

• The video explains the concept and shows you how to do the lab work:

Ch 17 & 20 – one-sample t test

• Submit your lab work as one single PDF file to Canvas before the due date.
