Level I CFA Quant: Hypothesis Testing-Lecture 3

This is Reading 11 for the 2021 exam.

[AD-ffmo]

Can you add intro linear regression here as well?

[akmaljanrakhmetov]

Thank you sir, for excellently explained course on statistics!

In the first example, depending on how you set your null hypothesis your conclusions will be different, right? If your H0 is that variance is less or equal to 6 you will also fail to reject it since 13.19 is lower than 30.144. This shows the uncertainty regarding this sample size and variance values, and the importance of setting your H0 correctly .

Since Chi Squared statistics is more than Crtitical value shouldnt Null hypothesis be rejected ?? Thats what we had learnt in Lecture 1

[shivanivasudevan]

thank you so much for your amazing lecture sir I was so worried about this reading you explained it on a easy manner thank you!

[yusu]

So helpful. How to access linear regression courses? Is it possible to upload those as well? Thanks!

[zahidakil]

As mentioned by sir population must be normally distributed but tests are bound by zero in the bottom which means f and chi test follows lognormal distribution. Can somebody tell me if i am wrong?

[shantanujoshi]

Sir in this case we are rejecting h0 when test statistic is less than the critical why is that

[cleow]

If we know the "true population variance", why are we hypothesizing about it? In what situation would we actually use variance tests if we already know the true population variance?

[anamikayadav]

sir for F-test isn't the critical value is 2.58?

[aidanhedley]

are these tables and others of hypothesis testing going to be provided in the exam?

[Wyt_Rabbit]

Thanks once again. I would recommend you add a $ Thanks button so we can send a cash thanks!
