I find 7.223 using the same calculation as in the answer sheet. Can someone explain why the correct answer is C ?
Any complaints?
Can anyone provide a full explanation/calculation? I seem to make a mistake at taking the derivative of each lagrange. I get for derivate of g: p^2 - 50/sqr root g * lambda and the answer say something different but basically the same....
On the success formula slides for Maths, Page 23. How did the last row become 0 10 12
i get we used gaussian elimination but why?
Regarding question 2, Why dont we use pooled t test? sample variance man/woman is smaller than 3.
You se it only when they are very close to each other. The rule of 3 does not apply! Usually exam questions are made in such a way that it is clear that the variances are the same and so you can use the pooled.
Can someone explain how to answer this question?
statement: dutch are more likely to stay at home and non dutch more likely to get housing --> so if this statement is true , (more dutch people stay home --> housing 0) you can say obs10>exp10 cuz. (You observe more people then was expected.) Apply this way of thinking with the given info in the answer and you'll find answer D.

i don't understand how to find answer b)
Does anyone have the answers to the end of chapter excercises for week 1? They don't match the answer key posted on UM Portal. Is this the same for every week?
could anyone explain how to get s, I manage to get to w, but when plugging it into the constraint I dont seem to get to the answer.
can anyone explain how to get to r'(k)=-1/2 ?
Isn't the second derivative of L''yx = 1 - 2Lagrange ? It's noted as 1 - Lagrange
You're right it should be 1-2Lagrange
can someone upload the answers to the inchapter excercises week 7? struggling hard time here
Shouldn't this be: -2?
How can we prove that the number of legal projects + number of reorganization projects is always equal to 4 ?
I don't understand why is AB^2 not well defined...?
A is a 3x3 matrix, B a 3x4. So, AB^2 means 3x3 3x4 3x4 which is not well defined since you cant break it down to 1 term like 3x3 for example
should be "not" instead of "now"
anybody got week 6 in chapter for math?
-qm2 tutoring- Hello everybody, I already posted here that I give qm tutoring. I was booked out completely but from now until the exam Iâ€™ll have additional availability on Sundays and Mondays if anybody needs help. I have 4 years experience doing private tutoring and also worked for the university. Just send me a message on Facebook (Lynn Se) or whatsapp (+491789149648) if you would like more info.

Check the QM course for IB
Any ideas of complaints?
Question 17 of stats says it is about proportionality, but then says we should use a t-stat even though t-stats are only for means. Is that a possible complaint?
they are using the F-test and not the t test

How to solve 16?
take derivative with respect to age= 0.016-2*0.00014age and solve for age (57=B)
Does somebody have the crash course slides for math and would be so nice to share them?
The only way to higher the grades is for many people to fail.. did a lot of you guys fail? I did..
I also failed, only with 1 point, and I need that point on stats :/
Sorry to hear that, how about the others?
Complaints? Missing one point
Anyone knows if we can get 1 additional point for complaining (on stats) ?
We have completely different formula in the sheet of the exam... How I was supposed to know it?
I got 10.89! So what is correct 10 or 11? I am obsessed with these questions
must be 11, as it takes xou more then 10 years to exceed the amount of 20 million on your savings account
how to solve this?
You just need to look at the determinant criterion, which says that you have a maximum whenever the determinant is bigger than zero. This is only the case at point x2,y2. Thus these points solve the maximisation problem. It's b
Can anybody explain how you solve this?

Can you explain how you found P value! I also found F statistic but how to transform it in P?
You just have to check the different F-Tables. They give you a F-Table for 1%, 5% and 10%. For these percentages, you check the df in the numerator (2) and in the denominator (34). After checking the 3 tables you'll realise that your p-value has to be larger than the 10%
Can someone explain me how to know how many stationary points a Lagrangian function has?
just the derivatives of each variable i believe
Do you know how to solve questions 1 and 4?
there are the answers at the end of the document usually! They explain the development!

When should we use the substitution method? Thanks mate good job!!!
Hi Henry, you can use the substitution method when one variable can be expressed in term of the other. So that mean when the constraint can be simplified
Good luck for Tommorow!

can someone explain how you know whenever you at which significance level you can reject a p-value? (maybe with a picture of an example?)
it usually is at the 1%, 5% or 10%. That means if your p-value is less than .01, .05 or .10, respectively, you reject Ho. However, if the question does not specify what the significance level is, you usually take 5% by default, this because, according to the empirical rule. for a normal distribution, we expect 95% of data being within 2 Standard Deviation from the mean.
Someone the answers of Math exercises Week 5 (Fiscal) Economics?
If you look at the practice exercises they're the same, but with different answers. Those answers are found on the course materials page (week 5)
would somebody be so nice and post the math tasks for week 6

Do we get those formulas during the exam? Or should we study them by hard?
