We will start Ch 9 Introducing Probability.

Starting from Ch 9, we switch from merely exploring data (Ch 1, 2, 3 & 4) 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 13).

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

 

 

Instructions

There are 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.

• • #9.7

 

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