Calculate a 95% confidence interval for the average height of US women using a random sample of 100 women where the sample mean is 63 inches and the sample standard deviation is 3 inches, and interpret this interval in context of the data.
Your lectures have been so helpful! I only wish you indicated which title we should watch next, so that I could watch them in order and build from the previous lesson. They really are great though!
I know Im randomly asking but does any of you know a method to get back into an Instagram account..? I was stupid forgot the account password. I love any tricks you can give me!
@Layton Lian Thanks for your reply. I got to the site thru google and I'm waiting for the hacking stuff atm. Takes quite some time so I will reply here later when my account password hopefully is recovered.
I'm pleased that I happened across this. I'm what you would call borderline mathematically illiterate. Stats is the last course to finally finish my post-secondary education. I have failed it thrice. Not for lack of trying. I'm hoping that with your help I won't have to go back again.
i wish your vedios goes as statics 1 , 2 . 3 ... and like that. because i am having a hard time to find the the next vedio of this topic. Thanks for this anyway.
Aw this is a professional teaching of the cofidence intervel. The way I see you working it with your hands with out calculated is great and simple sir.nice explanations.
OMG!!! I am so grateful that I found your video. You are the only one that made this make sense & not over-complicated. I'm a online student & I didn't understand my professors live session either. He had an Excel sheet & was clicking all fast (mind you pre-recorded) & just throwing numbers, no problems, nothing. I'm so lost!!! Your video made sense though. Thank you so much for posting.
Can you please solve this one. A report by the Ottawa Banking Association claims that the average monthly mortgage payment in Ottawa is $l,505. Assume that the standard deviation for monthly mortgage payments in Ottawa is $368. A random sample of 55 homeowners in Ottawa was selected and found to have an average monthly mortgage payment of $1,605. Identify the Upper CI, Lower CI, and Standard Error rounded to a WHOLE NUMBER (no decimals).
A 95% confidence interval for the average of a population is computed from a random sample and found to be 20±3. Which of the following statements is true? 1. There is a 95% probability that the sample average is between 6 and 12. 2. There is a 95% probability that the true average is 9 and there is a 95% chance that the true margin of error is 3. 3. that the true margin of error is 3. 4. If we took several additional random samples and calculated the average, 95% of the confidence intervals, approximately 95% of these intervals would contain the population average can you tell me how to solve this problem ?
I hate stats/quantitative methods because it’s not even a matter of your mathematical logic. Apart from this section, I feel like it’s mostly theoretical ideas/ concepts and that’s the worst when it comes to arithmetic (in my opinion). I used to be an 80-90 student in math and I never really did homework in HS, now I’m just below a passing grade and I find I need as much extra practice as I can get.
absolutely, professor told me that population can prove me guilty for 30 seconds. however, in reality, for me to be proven another true guilty if i love to, professor recommends me come back for million years for that population growth, unless it is recertified, then why not take the new one. Professor said stop bother, love that professor 'again time and space matter.' can i serve anything drink or food?quick
thanks sir for helping me understand HYP. Please help me solve this. Chicken Delight claims that 90 percent of its orders are delivered within 10 minutes of the time the order is placed. A sample of 100 orders revealed that 82 were delivered within the promised time. At the 0.10 significance level, can we conclude that less than 90 percent of the orders are delivered in less than 10 minutes? am grateful sir.
Hi dear and thx for ur videos, they are helpful as I had to skip my stats exam becos i never understood these concepts. Thanks a lot but where can i acess the entire videos to download for free. I will be very grateful as i have my exams i weeks time.
This information was very helpful. I was a little confused with the less than and greater than sign he has them bothe as less that. Still good clearly done.
not true. If they couldn't speak the language well, they would not be allowed to teach...having an accent is a totally different thing and I don't believe an accent is a barrier... @@nicnotnick
I you made me have an A in econometrics,because your teaching is very very clear and understandable I appreciate please keep on this work good.You have reminded me of my professor I had thank you.you deserve a hand.

Thank you! The best teachers know how to break things down, and you did that!
You sir have been sent from our ansestors
are you still alive
Ancestors?
Nyc teaching method☺
lol!!!!
SinatraWee wht lol??? If u r unable to understand him thn actually its lol😃
your videos are great but after that central theorem it is difficut to find video serially

How did it later went 7years ago?
Sir, you are gifted in what you do. Thanks for clearing my doubts. wow!
i wish your vedios goes as statics 1 , 2 . 3 ... and like that. because i am having a hard time to find the the next vedio of this topic. Thanks for this anyway.
very good, however, I'm not quite sure why you aren't doing/writing down the checks on the data.
The statistics course in my degree is fucking insanely hard.... everything I find on youtube is too basic. Im fed up reading it out of textbooks :(
i love you
Awwww!
Where can you view the rest of the statistics videos in playlists. They cut off after 3 minutes!!?
This was so helpful!! I have a statistics exam tomorrow and I am very sure, if I'm presented with such a question, I will ace it!!🥳🥳🥳Thank you sir👏
Aw this is a professional teaching of the cofidence intervel. The way I see you working it with your hands with out calculated is great and simple sir.nice explanations.
Thanks for this Sir
Wanted to clear my doubts before exams and am okay now
One of the clearest instructional videos , thank you
I really appreciate it!
if you say true population mean lies in between sounds like bayesian perspective, and as if there are many true population mean

You make it so easy to understand
My instructor data is just everywhere. I dont have a specific set of data like this
Can you please solve this one.

Lower CI, and
Standard Error rounded to a WHOLE NUMBER (no decimals).
Thanks
Yes, Sir, you have Simplified it easy to understand Great job EXPLAINING and BREAKING IT DOWN. yes, I have SUBSCRIBED THANKS......👋👋💥👋👋👋👋👋👋👋
But what is the point in solving just two questions of the same type.
I've never hated and needed something so much in my life.
Math and Science, but on your t-shirt it says Science and Math
A 95% confidence interval for the average of a population is computed from a random
sample and found to be 20±3. Which of the following statements is true?
1. There is a 95% probability that the sample average is between 6 and 12.
2. There is a 95% probability that the true average is 9 and there is a 95% chance
that the true margin of error is 3.
3. that the true margin of error is 3.
4. If we took several additional random samples and calculated the average, 95% of
the confidence intervals, approximately 95% of these intervals would contain the
population average
can you tell me how to solve this problem ?
I watched the whole Mastering Statistics - Vol 3 list
Ill give you a treat for all that I have learnt from you!!
Thank you so much!

How to write coclusion about the population mean using a 95% confidence interval?
I am in 6th grade please answer i need this for my exams.
Mate i need to give you some of my uni tuition fee coz atm you're teaching me.
your comment made me laugh LOOL

Hi , i am having trouble understanding this?
i am sittng with a problem and annot find the solution...please help
This information was very helpful. I was a little confused with the less than and greater than sign he has them bothe as less that. Still good clearly done.
thank you so much. wish you were my actual teacher considering mine is forign and cant elaborate
Apparently you are foreign too 'cuz you can't spell.
why do you feel necessary to bring out that she is foreign???
@@Cubanmuchacha because foreign teachers often can't speak the language very well, and are hard to understand.
not true. If they couldn't speak the language well, they would not be allowed to teach...having an accent is a totally different thing and I don't believe an accent is a barrier... @@nicnotnick
this was amazing sir, good work!
lol, 15.7 hours a year maybe.
I am definitely ordering this to help me with my class this is awesome
ok this is perfect...just...how do u find the margin of error? might have that in my notes
good stuff. looking for the moe vid
Excellent explaination
I you made me have an A in econometrics,because your teaching is very very clear and understandable I appreciate please keep on this work good.You have reminded me of my professor I had thank you.you deserve a hand.
Thanks, another related question is following: is it possible to compute the exact p-value of an estimate given the confidence interval?
how to do i get a discount on your math tutor dvds?
Amazing video again. So easy to understand. Thank you
thank you
Your lectures are absolutely awesome! Thank you very very much :)
Glad you like them!

i dont get the condfidence interval percentages, they seem irrelevant throughout the examples?
Very cool.
