Anyone at SFU right now?

Barely any DIAGRAMS whatsoever, just pure explanation in words.

Econ 103 with Doug Allen in my FIRST semester... worst decision I made, got wrecked.

[SNSD]

doug allen is really funny and his lectures are never boring XD

[The_AK]

Doug Allen is actually one of my favourite profs, although some people find his class difficult I thoroughly enjoyed it

Hey guys how do we get our T4As? When I click it in the SIS I get No T4A Data available.

I started in september 2011 and ended in dec 2011. Would that be for next years taxes?

[bobbinka]

T4A is for scholarship amounts

if you're looking for your tuition amounts, it's the T2202A

Doug is the bomb!

assignment 2 for bus 237 looks like its alot of work...totally not worth the 5%..

[haha13]

Just looked at it now... so much work.

[Porschedog]

Although Doug Allen's class is hard, I found his lectures enjoyable.

'mirin

[jtanner_]

^ wat.

Wuz dat dere mirin?

Mirin (味醂 or みりん?) is an essential condiment used in Japanese cuisine, consisting of 40%–50% sugar.[1] It is a kind of rice wine similar to sake, but with a lower alcohol content—14%[2] instead of 20%. There are three general types.

M/C was fair

Short answer gets tricky. Lots of room to lose marks in this section.

Anyone here in Nebile barkin's econ 103 class. What did you think of the midterm ?

God I really hate her. She over complicates everything in her explanations. Damn her.

[EvoFire]

100% for Buec 333 right now. 100% for first two assignments, 100% for the midterm, ooh what a feeling!

EDIT: Take 333 with Ramazan Gencay guys, its pretty damn good.

Oh yea, did you see two different (writing) styles in your marking. She would force the TA to mark all of it within 24 hrs and then remark it herself. Shes a fucking troll.

Anyone writing stats 201 exam tmrw wanna study? I'll be on first floor library. I'm so full of fuck with the practice Q he posted online. Anyone wanna check my answers? I'm foreveraloning in that class.

Spoiler!

Ex:

A die is rolled it n times. Let Xk = the spots recorded on the kth roll and X = X1 + X2 + …+ Xn = sum of spots resulting.

Q1. Roll the die twice (n = 2). Describe the sample space.

Q2. Find the mean of X1 and the variance of X1.

Q3. Are the first roll and the second roll independent? Are X1 and X2 independent?

Q4. Roll the die twice (n = 2). Find the sampling distribution of X = sample total = X1 + X2.

Q5. Roll the die 100 times. P[3.5 ≤ ≤ 3.9] is ______________.

Q1)
Sample space is as follows (given by Totals)
2 with P(1/36), 3 with P(2/26), 4 with P (3/36), 5 with P (4/36), 6 with P (5/36), 7 with P (6/36), 8 with P (5/36), 9 with P (4/36), 10 with P (3/36), 11 with P(2/36), 12 with P (1/36)


Q2)

To find the mean of X1 and the Variance of X1, is it just:


Common Mean = E(X1) = Mew (U)

E(X1) = (1 * P(x1=1))
+ (2 * P(x1 = 2)
+ (3 * P(x1 = 3)
+ (4 * P(x1 = 4)
+ (5 * P(x1 = 5)
+ (6 * P(x1 = 6)

=3.5 = Mew


Common Variance = V(x1) = E{[x1 - E(x1)]^2}
*Where E(x1) = Mew

=
(1-3.5)^2 * 1/6
+ (2-3.5)^2 * 1/6
+ (3-3.5)^2 * 1/6
+ (4-3.5)^2 * 1/6
+ (5-3.5)^2 * 1/6
+ (6-3.5)^2 * 1/6
=2.916 = Sigma Squared


Q3)
Yes indépendant because P(any outcome) = 1/6 for both X1 and X2

Q4) If die rolled twice (N=2) Sampling Distribution of X is = sigma^2/n which is

2.916/2 = 1.458
** I'm going by his wednesday lecture notes here where he stated several times Common Variance of X1 = Sigma^2, and that Variance(Xbar) = Sigma^2/n


EDIT: I'm a retard I read his notes wrong -.- I hate Scott Pai I don't understand why he throws so many equations at us .. I seriously had less equations in physics -.-

It's actually Sqrt(2.916)/Sqrt(2) = 1.207
Q5) Die is rolled 100 times,
P[3.5 ≤ ≤ 3.9]

The distribution is Approx. Normal with N[Mew, Sqrt (Sigma^2)/ Sqrt(n)]
Therefore, N[3.5, 0.17076]


(3.5 - 3.5)/0.17076 [LessthanEqualto] Z [LessthanEqualTo] (3.9-3.5)/0.17076

0 ≤ Z ≤ 2.3424

=0.9904 - 0.5 = 49.04%

i have a feeling I'm way off

If any RS-ers wants to study for stats 201 my email is dhillon09@gmail.com (I check that way more than RS) so just email me your number and we can meet up!

Anyone ever take Econ 103 with Jun Choi or 105 with Eldar Sehic? I read some ratemyprof reviews and both check out pretty well. I need another Q credit, so I'm trying to figure out which class is easier because I'm pretty bad at doing math but need to fill out the WQB.
