Confidence Interval for Population Means in Statistics
Get the full course at: www.MathTutorDVD.com
In this lesson, we'll discuss the concept of the confidence interval in statistics. We'll solve a few problems where we must calculate the confidence interval of a population mean when given information such as the sample size, margin of error, and the sample mean..

Sir, you are gifted in what you do. Thanks for clearing my doubts. wow!
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.
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 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!
I am definitely ordering this to help me with my class this is awesome
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.

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.

Thanks, another related question is following: is it possible to compute the exact p-value of an estimate given the confidence interval?
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👏
Simply explained. Thank you!
Thank you sir. Your tutorial video is so in detail and it is easy to understand.
this was amazing sir, good work!
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.
The clearest and simplest explanation. Thanks
Thank you for this... it really helped me a lot for my report. 👍
I wish I could like this a thousand times!!
Thank you for this video it helped alot! great teacher!
YOUR EXPLANATIONS ARE EXCELLENT
do you have a video where its done with Sample mean?
Thank you, working on my Doctorate and this is very helpful.
thank you so much for explaining it clearly and calmly, I am confident that I will pass my exam now,
THANK YOU !! IT HELPS A LOT FOR MY AP CLASS
You make it so easy to understand
Amazing video again. So easy to understand. Thank you
Thank you sooooooo much! This saved me the day before my final!
How did you make your Cover Video???
Excellent explaination
ok this is perfect...just...how do u find the margin of error? might have that in my notes
how to do i get a discount on your math tutor dvds?
love your teaching! :)
Thanks for this Sir Wanted to clear my doubts before exams and am okay now
The lecture is on point.
prev video link?
I've never hated and needed something so much in my life.
thanks sir, loved the video!
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.
Ill give you a treat for all that I have learnt from you!!

very good, however, I'm not quite sure why you aren't doing/writing down the checks on the data.
Yes, Sir, you have Simplified it easy to understand Great job EXPLAINING and BREAKING IT DOWN. yes, I have SUBSCRIBED THANKS......👋👋💥👋👋👋👋👋👋👋
Bless you for this video:)
your videos are great but after that central theorem it is difficut to find video serially
Thank you very much
Thank you Sir!
Where is the second part to this video
Thank you!
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 , i am having trouble understanding this? i am sittng with a problem and annot find the solution...please help
thank you
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.
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).
thank you sooo much

sir is that given of 95% confidence interval
I watched the whole Mastering Statistics - Vol 3 list
How to get marginal error ?
thanks
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.
But what is the point in solving just two questions of the same type.

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.

Awwww!
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 ?
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
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.

i dont get the condfidence interval percentages, they seem irrelevant throughout the examples?
Oooh, sweet Jesus!
Math and Science, but on your t-shirt it says Science and Math
if you say true population mean lies in between sounds like bayesian perspective, and as if there are many true population mean

Errr this is so simple
