student	1200pi/1 minute * 9ft * 1mile/5280 ft	7,645	140	[]
volunteer	yup	7,645	141	[]
volunteer	whats the final value?	7,645	142	[]
student	386 mile/hr because we also multiple by 60min/1 hour	7,645	143	[]
volunteer	and you forgot to convert one thing	7,645	144	[]
volunteer	yup	7,645	145	[]
student	yay	7,645	146	[]
volunteer	you got it	7,645	147	[]
student	confetti!!!	7,645	148	[]
student	yay	7,645	149	[]
volunteer	yup	7,645	150	[]
student	okay wait thank you so much	7,645	151	[]
student	I get it better now	7,645	152	[]
volunteer	you got it Maya	7,645	153	[]
student	I'll just keep doing problems and applying the knowledge	7,645	154	[]
student	Wow!	7,645	155	[]
volunteer	but do you know why are you converting 600 rpm to radians per min?	7,645	156	[]
student	well it asks for the final answer to be in mph	7,645	157	[]
volunteer	yup	7,645	158	[]
student	yay	7,645	159	[]
volunteer	but why you covert that?	7,645	160	[]
volunteer	because	7,645	161	[]
volunteer	600 is the no of spin	7,645	162	[]
volunteer	not the distance	7,645	163	[]
volunteer	so we convert that spin to the distance	7,645	164	[]
volunteer	thats why	7,645	165	[]
student	yea	7,645	166	[]
student	thanks	7,645	167	[]
student	I get it	7,645	168	[]
volunteer	you did really well	7,645	169	[]
student	thank you that's so kind. it was thanks to you	7,645	170	[]
volunteer	best of luck Maya	7,645	171	[ { "pii_type": "PERSON", "surrogate": "Maya", "start": 13, "end": 17 } ]
student	Also do you happen to be Indian	7,645	172	[ { "pii_type": "NRP", "surrogate": "Indian", "start": 25, "end": 31 } ]
volunteer	you are most welcome	7,645	173	[]
student	just curious because of your name	7,645	174	[]
volunteer	yup	7,645	175	[]
student	oh my gosh same	7,645	176	[]
volunteer	you too?	7,645	177	[]
student	I'm Pakistani	7,645	178	[ { "pii_type": "NRP", "surrogate": "Pakistani", "start": 4, "end": 13 } ]
volunteer	same	7,645	179	[]
student	I had a classmate named Anaya when I was younger	7,645	180	[ { "pii_type": "PERSON", "surrogate": "Anaya", "start": 24, "end": 29 } ]
student	just spelled differently	7,645	181	[]
volunteer	ikr	7,645	182	[]
student	so I was curious	7,645	183	[]
student	oh okay twinsss	7,645	184	[]
student	okay thank youuu. good night!	7,645	185	[]
volunteer	it's a very common name except I am a girl	7,645	186	[]
student	OHH ME TOO	7,645	187	[]
student	okay that's so surprising because I didn't realize it could be used for girls as well	7,645	188	[]
volunteer	yup	7,645	189	[]
student	My names similar except it's more feminine since it has an a at the end	7,645	190	[]
volunteer	yes	7,645	191	[]
student	that's so cool	7,645	192	[]
student	okay thank you!	7,645	193	[]
student	good night	7,645	194	[]
volunteer	nice to meet you	7,645	195	[]
volunteer	good night	7,645	196	[]
student	nice to meet you too :)	7,645	197	[]
volunteer	OK, I hope you can hear me	7,729	0	[]
student	Hey, I would like to um deepen my understanding for in statistics for Chapter 5 on hypothesis testing with the means of the sample.	7,729	1	[]
volunteer	Right. And you said you had a practice problem, right?	7,729	2	[]
student	Yes	7,729	3	[]
volunteer	OK. Are you able to show me the practice problem and we can try it.	7,729	4	[]
student	Let me just	7,729	5	[]
student	OK	7,729	6	[]
student	1. Why is the standard deviation of the distribution of means generally smaller than the standard deviation of the distribution of the population of individuals? 2. For a population that has a standard deviation of 10, figure the standard deviation of the distribution of means for samples of size (a) 2, (b) 3, (c) 4, a...	7,729	7	[]
volunteer	Let	7,729	8	[]
student	These are the questions I want to practice first.	7,729	9	[]
volunteer	OK	7,729	10	[]
volunteer	All right	7,729	11	[]
volunteer	OK, we can start with the first question. Do you have any, any gas?	7,729	12	[]
student	Is, um, so the first one is because um	7,729	13	[]
student	the um	7,729	14	[]
student	it's because it wears among the um among the population.	7,729	15	[]
volunteer	Yes, if you have um	7,729	16	[]
volunteer	if you have a population of, of individuals and you just take	7,729	17	[]
volunteer	the value of one	7,729	18	[]
volunteer	one person	7,729	19	[]
volunteer	that can vary a lot, but when you take the mean, you add up	7,729	20	[]
volunteer	data from many people like can be a large sample.	7,729	21	[]
volunteer	and then you divide by the number of data points and that's your sample mean. So it's very difficult for that to vary. It will vary much less so that when you calculate, for example, if the standard deviation	7,729	22	[]
volunteer	of the population.	7,729	23	[]
student	Well, the answer is that it bears among the population, um.	7,729	24	[]
student	right.	7,729	25	[]
volunteer	Well, it varies among the population, but the sample mean will vary much less	7,729	26	[]
volunteer	than the individuals in the population.	7,729	27	[]
volunteer	I'll, I'll give you an example. I'll, I'll write on the board, if you have, if you have a variable x, you see what I'm writing on the board?	7,729	28	[]
volunteer	So let's say the standard deviation of X	7,729	29	[]
volunteer	is sigma, then if you	7,729	30	[]
volunteer	look at the	7,729	31	[]
volunteer	sample mean, so that's x bar. Do you see that?	7,729	32	[]
student	Yes, I see that	7,729	33	[]
volunteer	OK. So, this is, this is.	7,729	34	[]
student	That's also called the um the variants, right?	7,729	35	[]
volunteer	uh no, the variance is something else. The variance is the square of the standard deviation.	7,729	36	[]
volunteer	So the sample mean	7,729	37	[]
student	And the X bars the sample mean.	7,729	38	[]
volunteer	that's right	7,729	39	[]
volunteer	And when you calculate the standard deviation of the sample mean, that will be	7,729	40	[]
volunteer	sigma, which is the standard deviation divided by the square root of N. N is the sample size. So when you divide by	7,729	41	[]
