Sequence Comments

For the test tomorrow make sure you can fill in gaps in a sequence
For example 2, ___, ___ 16, ... is a geometric sequence find the missing terms, then write the recursive rule.

(Note missing numbers are 4, 8 and recursive rule is T(n+1) = 2T(n); T(1) = 2)

The questions also include finance type contexts so make sure you know percentage increase type questions and be able to use general rules to describe them.

Good luck and see you all in the morning.

Normal distribution

Make sure you understand the concept of normal distribution and the 68%, 95%, 99.7% rule when balanced.
a good practice is to watch the video from http://www.classpad.com.au/

here are the class notes

Sampling Techniques

Here are the notes on sampling. You need to be able to describe how you you would choose a sample.
