## Week 9

We made a good start on probability, talking about random variables, independence, mutual exclusivity, conditional probability, and tree diagrams.

## Week 10

We will have a lot of probability to do — reliability block diagrams, the binomial distribution, the Poisson distribution.

You have a sample Maple Test with solutions (*the first with(Statistics) should be with(LinearAlgebra)). The Maple Test will not include anything from Chapter 2.

We do not have enough probability done to have a Maple Lab until…

## Week 11 – Maple Night

We will look at the normal distribution and talk about sampling.

## Week 12 – Maple Test

We will speak about sampling in more detail and also introduce control charts.

The Maple Test will be open book and you will have already received a sample test with solutions.

## Week 13 – Review

We will hold a review class on Wednesday 9 May in the usual room. First off, the layout of your exam is the same as Autumn 2016 (in the back of your notes): do question one worth 50/100 and two out of questions two, three, four; each worth 25/100.

I will field any questions ye might have at this time and if there are no questions we will do this exam paper. The best possible thing for your study is to do this exam paper and then on Wednesday see how you got on.

## Maple Catch Up

If you have missed a lab you have two options: either download Maple onto your own machine (instructions may be found here) or come into CIT at another time to use Maple.

Go through the missed lab on your own, doing all the exercises in Maple. Save the worksheet and email it to me.

## Independent Learning

Questions you can do include:

• After Week 9: P. 92, Q. 1-10 (not too important); P. 96, Q. 1-6 (this is loads: more is Q. 7-13)
• After Week 8*: P. 89, Q. 1-3
• After Week 7*:  P. 89, Q. 1 (a), (b); Q. 2 (b); Q. 3 (b)
• After Week 6*: P. 74, Q. 1-4; P. 77, Q. 1-3
• After Week 5*: P.44, Q. 1-3, Q. 4-5 more abstract. P.47, Q. 1-3, Q. 4 more abstract.  P.56, Q. 1-3, Q. 4 more abstract. P.69, Q. 9 is an important question. A $2\times 2$ version might be

Use only determinants to determine if the following homogeneous system of linear equations has non-zero solutions:

$2x+y=0$

$-6x-3y=0$

• After Week 4: P. 41, Q. 1-4
• After Week 3: P. 28, Q. 1-5, 6-9 have answers with Q. 7 a harder question. P. 34 exercises.
• After Week 2: P. 18 Q. 2
• After Week 1: P. 18 Q. 1, 3 – 6. Harder questions are 7 and 8. For those who do not yet have the manual, see here.

I am not suggesting you should do all of these. It is recommended by the module descriptor that you do two hours of independent and directed learning every week but of course this isn’t feasible for everyone.
