We will start Ch 12 Introducing Probability.

Starting from Ch 12, we switch from merely exploring data (Ch 1, 2, 4 & 5) to drawing or conclusions about the data that we gather. The process of drawing conclusions based on the data is called statistical inference.

You will notice that things start to get more abstract (the most abstract chapter is Ch 15).

Probability is a abstract and difficult topic. However, we will focus on the basics.

 

Instructions

There is 3 problems in this lab work:

• • problem not in book (the idea of probability)

• • problem not in book (construct a probability model)
    • You MUST show what the total sum of the probabilities is.
    • Take 4 decimal places for each probability number. Due to round-off errors, the total sum of the probabilities might not be exactly equal to 1 e.g. your sum might be 0.98. That’s OK. But you MUST write out what that sum is equal to.

• • #12.10  (Use the numbers shown in the video, which is the 9th edition)

 

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

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