12 SL: Intro to Statistics

Read Chapter 11 of the red textbook and come prepared after the break with any questions you have about that material. Pay particular attention to 11B (the definitions in 11A for types of sampling error are less critical, but you should be able to recognize when a sample is likely to be biased).

Then, complete the following questions.

Exercise 11D questions 2 and 4
Exercise 11F question 1

Exercise 12A questions 2b and 13
Read section 12B.
Exercise 12C questions 2 and 5
Exercise 12D questions 6 and 7

11 HL: Vector Equations of Lines, etc.

Complete the questions below before tomorrow’s class.

Exercise 12N.3 questions 2, 5
Exercise 13C question 8
Exercise 13D questions 3, 5
Exercise 13E question 5
Exercise 13F.1 questions 1de, 8, 9 (you don’t need to use row reduction here)
Exercise 13F.2 questions 1de
Exercise 13F.3 question 1b (this is a challenge question)

11 HL: The Cross Product

Complete the questions below before our next class.

Exercise 12N.1 questions 1, 4, 8, 10
Exercise 12N.2 questions 3, 4, 5

We haven’t talked about the content of this next section, but if you want to get a head start you can have a look at the questions below.

Exercise 12N.3 questions 2, 5

12 SL: Probability Distributions & Expectation

Complete the following questions before our next class. (Note that you will need to do some reading in Sections 20B and 20C.1 to complete these.)

(Black Book)

Exercise 20B questions 3, 4, 6
Exercise 20C.1 questions 2, 5, 6, 8

11 HL: Vector Equations of Lines in 2D

Do your best to complete the questions listed below before our next class (we’ll continue working on these in class on Monday).

  1. Find a vector equation of the line with Cartesian equation \(y = \frac{3}{4}x -2\).
  2. Find another correct reponse to question 1 that uses different values for both \(\vec{a}\) and \(\vec{b}\).
  3. Find the Cartesian equation of the line \(\vec{r}=\begin{bmatrix}4\\-1\end{bmatrix}+\lambda \begin{bmatrix}1\\2\end{bmatrix}\).
  4. Find a vector equation of the line passing through \(A(1,3)\) and \(B(2,-1)\).
