Yes.. that is correct.

Hi Dr. Miller! I'm still trucking right along.  I am working on the Roofing Case now.  I'm forming the alternative hypothesis and I believe that it is p is greater than .20 because the insurance agent is trying to determine if the bad roofing company was involved and responsible for the claims. Is this the right track?

Random Comment:  Quizzes today were EXCELLENT.. just outstanding... I really thought Quiz 3 might be tougher than Quiz 1/2.. but the grades went UP on Quiz 3.. I am SUPER pleased with quizzes so far.

Again.. it's not major..and I know each of you is fighting so hard with vocabulary.. so I hate to sound picky like that... but that's such a central "step" in the process that it's important to call it "sampling distribution" and leave the word "sample"  to it's own use...

I honestly was not aware of the difference, thanks for the heads up on that. I'll keep an eye out for it from now on.

I know that seems inconsequential.. but you'll see what I mean in a video next week... it's not a big deal for now.. but you might try and focus on term "sampling distribution"... and of course, it was probably just you typing things in here... and knew that's what it is called... just pointing out a specific.
The term is "sampling distribution" as opposed to "sample distribution"...

Not to be too picky... but this will come up in a video next week...
7:13
By the way.. .

That clears things up a lot. Thanks for the help!

Probability distribution is just a little "wider" term that takes in more contexts.. so yes, your explanation is fair enough
7:12
A sampling distribution is a type of probability distribution... yes...

Ah okay, so this is synonymous with the sample distribution talked about earlier in the lectures but "probability distribution", is used to include density curves if they are necessary.

The probability distribution is a complete set of calculations or a complete drawing of a curve.. that lists all possibilities and and all probabilities collectively.. does that clarify?  Or, does it need additional clarification or such?
7:10
once all those probabilities had been found.. you'd have the ENTIRE probability distribution.
This would mean that you would need to find the probability of EACH possible outcome.. 0, 1, 2, 3, 4, 5, and 6...
7:09
If someone asked you to "FIND" the probability distribution when the sampling distribution is Binomial with n = 6, and p = .80...
For instance...
A probability distribution is the COMPLETE mass function or COMPLETE density curve to represent a situation..
7:08
This came up earlier today once too.. good question..

I wanted to ask what they mean in the book when they say about probability distribution
