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.
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.
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.
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.
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.
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).
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.
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.
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
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 ?
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.
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.
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.
