This is what I assume about annual maintenance.

like that one, this is not a particularly good hypothesis.

Olivia, this isn't like before.

And our null hypothesis is equals p 0.9 and our alternate hypothesis, if it doesn't work, as well as the null hypothesis, so p is smaller than 0.9.

From what I've seen so far, I am forming a hypothesis.

And actually especially after a big real estate boom, may be prudent.

Because we'll see later in this video that to some degree, that assumption is one of the biggest drivers of assumption.

(Laughter)

It could actually be 90 as advertised and you were just unlucky, but we believe that high probability of this is correct or is the data actually contradicting this claim and you should complain that the claim is incorrect.

So just khanacademy.org downloads buyrent.xls.

And you'll see what I mean because I'll change that assumption in a second.

linear in n. Remember in the quiz we saw is at least n minus 1 if you wanted the graph to be connected, and it's also big O of n squared.

Maybe I'll experiment doing it the other way. but let's assume this is g prime of x, and let's assume this f of x.

So how could you take advantage...?

You can change it.

Again, what do you think could help us get the right answer this time?

Setup Virtual Machine

Hypothetically.

The 2 , that's general inflation.

We finish this step for a search.

In the Extension box, type the file name extension you want associated with PHP scripts.

But anyway, don't want to get too complicated.

And what I want to do

Fortunately it stopped, not because anyone understood arithmetic, it stopped for other reasons.

Along this wall, y is a constant, right?

So this is all just running descriptives to figure out if you truly have normal distributions.

We know the the smallest angle is going to be ten degrees and I'll just say let's just assume that this right over here is the measure of the smallest angle.

It could be function of just y.

And all I did there was took the definition for my hypothesis and plug that in there.

We know from definition that 1 is equal to i times i. Everything seems pretty straightforward right now. And then they'll say,

So, let's go back to that normal distribution.

A very simliar to it, is so called expanding photosphere method for supernova.

And so that's how we get an infinite grammar.

Suddenly, it's not so hypothetical, is it?

In the next few videos, what

And what the marshmallow challenge does is it helps them identify the hidden assumptions.

There really is no correct answer.

So again, remember the idea of null hypothesis significance testing.

But for the sake of simplicity ... ... we're going to assume ... ... that it was kind of a constant velocity ... ... or what we are calculating is going to be his average velocity.

I think this concept, that we can positively impact our genes, is really profound and empowering because we've always worked under the assumption that our genes are set in stone, that they're beyond our influence.

looking at the coin.

Don't torture yourself with hypotheticals.

One, two, and three.

The last lecture, it will be all about how to do model comparisons.

So measuring the circular velocity as a function of radius gives us a direct estimation of the mass inside the radius and therefore what is the density as a function of radius.
