volunteer	No, no. The second population would be the people who have	7,729	542	[]
volunteer	had a traumatic experience.	7,729	543	[]
student	I have.	7,729	544	[]
student	traumatic.	7,729	545	[]
student	OK	7,729	546	[]
volunteer	OK	7,729	547	[]
student	And then I'm gonna state my research and the know hypothesis now. I first step.	7,729	548	[]
student	Mm.	7,729	549	[]
student	So people who have	7,729	550	[]
student	so it will be like people who have traumatic experienced um to um people who have traumatic experience will have, will have, um, will affect the conditions of their dream when they are alone, then um then the population in general.	7,729	551	[]
volunteer	Well, it, it's more specific than that. The what the psychologist wants to research is if people who have had	7,729	552	[]
volunteer	a traumatic experience will have	7,729	553	[]
volunteer	more than 5 dreams.	7,729	554	[]
volunteer	per night.	7,729	555	[]
volunteer	because the general population has 5 dreams every night.	7,729	556	[]
volunteer	on average. So	7,729	557	[]
volunteer	the research hypothesis is will people have had a traumatic experience, have more than that.	7,729	558	[]
student	So it will be like people who have traumatic experiences will have more dreams than people in general.	7,729	559	[]
volunteer	Correct	7,729	560	[]
volunteer	So it's still going to be a directional	7,729	561	[]
volunteer	a directional	7,729	562	[]
student	Yeah. Yeah.	7,729	563	[]
volunteer	because I think that's what you said. It's going to be a directional test.	7,729	564	[]
student	So I put like people who have traumatic experiences will have more more dreams will have	7,729	565	[]
student	more dreams when alone, then people in general.	7,729	566	[]
volunteer	Right, exactly	7,729	567	[]
student	I'm still on that one, OK?	7,729	568	[]
volunteer	OK	7,729	569	[]
student	Are you at home	7,729	570	[]
student	Mm.	7,729	571	[]
volunteer	Uh yes	7,729	572	[]
student	me too	7,729	573	[]
student	OK. I'm on step 2. So for the no hypothesis, I put people who have traumatic experiences will not have um	7,729	574	[]
student	more dreams when they are alone, then people in general.	7,729	575	[]
volunteer	Right	7,729	576	[]
student	And then step to figuring out the characteristics.	7,729	577	[]
student	So, the meal is 5, the variances	7,729	578	[]
student	wait, let me see.	7,729	579	[]
student	It's 4.	7,729	580	[]
student	and it's 36.	7,729	581	[]
student	And um the um the sample mean is 8.	7,729	582	[]
volunteer	Right	7,729	583	[]
student	which is also known as X, right?	7,729	584	[]
volunteer	Yes, for our purposes, yes.	7,729	585	[]
student	And then, so we had to figure out, so it would be again um 1.64, right?	7,729	586	[]
student	Positive.	7,729	587	[]
student	2	7,729	588	[]
volunteer	No, here it's gonna be positive because we want to know if the population with the group with traumatic experiences will have more	7,729	589	[]
volunteer	than	7,729	590	[]
volunteer	5. So the, the direction is the opposite of last time, so it's going to be + 1.64.	7,729	591	[]
student	OK	7,729	592	[]
student	Just the PY	7,729	593	[]
student	I.	7,729	594	[]
student	Mm	7,729	595	[]
student	If it was non-directional, it would be um positive and negative 1.96, right?	7,729	596	[]
student	Um	7,729	597	[]
volunteer	Uh, let me see	7,729	598	[]
volunteer	I'll let me check	7,729	599	[]
volunteer	OK.	7,729	600	[]
student	Like if we were to do 2 tilt tests.	7,729	601	[]
volunteer	Yes, you're correct. It would be a plus or minus.	7,729	602	[]
student	Yeah	7,729	603	[]
volunteer	Right.	7,729	604	[]
student	And then step 4 is um like when we had to compute the Z score now. So first, I have to um square root the 4.	7,729	605	[]
student	which is equals	7,729	606	[]
student	to scrambled up.	7,729	607	[]
student	is true. So, and then 2 divided by the square root of 36, which is the end.	7,729	608	[]
student	Right	7,729	609	[]
volunteer	That's right	7,729	610	[]
student	It's 0.33.	7,729	611	[]
student	That's the standard deviation of the means, which is like also the standard error.	7,729	612	[]
volunteer	The standard error, that's correct.	7,729	613	[]
volunteer	OK	7,729	614	[]
student	I call it the standard deviation of the means. SDM	7,729	615	[]
student	OK, now we can compute the Z score. So it's um	7,729	616	[]
student	8 minus	7,729	617	[]
student	5 divided by 0.33.	7,729	618	[]
student	3.	7,729	619	[]
student	I'm getting the Z score of 9.09.	7,729	620	[]
volunteer	OK	7,729	621	[]
student	OK	7,729	622	[]
student	So we will reject the no hypothesis then?	7,729	623	[]
volunteer	Definitely	7,729	624	[]
student	Like it falls in the um in the share shared, shared region.	7,729	625	[]
volunteer	Yes, it, it falls very far	7,729	626	[]
volunteer	into the shaded regions, so definitely we reject the null hypothesis. In other words	7,729	627	[]
volunteer	uh	7,729	628	[]
volunteer	in other words, it, it's very reasonable that people who had a traumatic experience will have more dreams than the general population.	7,729	629	[]
student	So it's very deep in the rejection region.	7,729	630	[]
student	Yeah	7,729	631	[]
volunteer	Oh yeah, because the rejection region starts at z equal to 1.64. We're at 9.0 something.	7,729	632	[]
student	OK. So we inject the hypothesis.	7,729	633	[]
student	Cause I try to understand this chapter from my classmates, but they couldn't really explain it to me like they were kind of like one lady was kind of like um she was like, sometimes the questions you ask, they don't make sense. They're really like frustrating.	7,729	634	[]
volunteer	Oh, you mean, you mean somebody on Up Chief said that?	7,729	635	[]
student	No, no, no, not here. Like somebody in my one of my classmates.	7,729	636	[]
student	OK	7,729	637	[]
volunteer	or one of your classmates, OK.	7,729	638	[]
student	Oh	7,729	639	[]
student	Here is, I just started yesterday. I just knew about this yesterday from the um from someone.	7,729	640	[]
student	Yeah. I just knew about this yesterday.	7,729	641	[]
