Study Session 3: Quantitative Methods: Application

Hypothesis Testing

I was reading Hypothesis Testing and didn’t get it at all. I also saw that in the Schweser notes they have mentioned that it is not to worry about the messy formulas and testing. I have wasted too much time wrapping it around my brain. And feel very frustrated because I am still not getting it.

TMV - Drawing time lines during exam

Hey there. I’m wondering for those who have taken, and preferably passed, the level 1 exam if you were taking the time to draw time line graphs when solving TMV questions. With an average of a minute and a half per question, there is not much time to waste. However, I know drawing time lines is makes these questions easier and reduces mistakes.
Should I focus on learning how to do these questions strongly without having to draw them? Or does drawing them, in your opinion, actually make the questions shorter in duration for you?

Probability Distributions - Quicker method?

Is there a quicker method to getting the correct answer? 
The questions is easy but the time it takes to get the answer is long. (Took me 2:47 and that was using the STO/RCL functions on TI BA II Plus) Just curious. Thanks

P = .7 , N = 7, X = 4
Find probability of 4 or fewer successes.

The correct answer is 35.3 percent.

Solving for r - Help with equation

Hi - I am drawing a comlete blank.

I know I can do the steps to get the answer (6.91%) on calc but want to understand this please.

Solving for r,

$1,000 + $3,165/(1+r) = $25/(1+r) + $4,500/(1+r)2

One or two tailed test for t test

How do you determine to use a one tailed or two tailed level of signifigance? What in the question do you base this off of?

null hypothesis

In the reading of 12.2, it says:

The null hypothesis is a proposition that is considered true unless the sample we use to conduct it gives convincing evidence it is false.

So why is this statement wrong:

The null hypothesis is the condition a researcher hopes to support?

calculate mean, variance and stdev

I’m on the quantitative part, i got the TI BAII calculator. But i find it still hard/time consuming to get mean and stdev for a data series. Getting mean is fine, except lot of pressing. But to get the stdev/variance, you will need to keep a lot of intermediate result, and this takes a lot of time, e.g. one of the practice problems had 13 data points. So what is the best/fastest way to calculate those parameters?

Suggestion for Quant

Hi,

So I am studying the Quants part now. TVM and IRR concepts are pretty clear and ok. But now when I have moved to Statistics, Probability etc it feels difficult to grasp. Maths was never my strong suite. So I would like to know how heavy in terms of wightage are these chapters in L1 and also in L2 and 3. Can I skip these and try to get some extra marks in some other topics?

Thanks.
