I am half way through my University semester doing introductory stats right now and your lessons are saving me so thankyou. I have 2 more stats courses to do in my degree as well as i will definitely be looking to purchase your mastering statistics DVDs. Thanks again :)

    My God, you are the best greatest teacher on earth, I don't know if there is or not anyone else that I know that teaches so clearly in detail, you should be an example to the entire world's education systems. The entire world education systems must be changed, this is how everything should be taught , instead of long boring lectures, or reading books that are so hard just to understand what they are trying to tell you, because the way books are written is very official language which I abhor, a simple concept that can take one minute to understand takes hours, because the way these evil books are written , the concepts of science, math and everything else are not hard to learn and are actually fun to learn, if it wasn't for these official languages that are used in all books, I am so sick and tired of them. This is how everything should be taught in all schools. Simple, fun and clear. They should learn from you, you are the best and made a big difference in my life, truly American teachers are the best too at teaching. But offcourse your ways of teaching makes it the 👌 best.

    Great vid, subscribed to your website-based lessons. Here's a question - What is a natural explanation of why the error is highest with p=.5, for a given Zc and n? In other words, as the factor of either p or 1-p approaches 0, the error goes down. Less likely events have lower error?

I have calculated the sample proportion and I need to calculate the margin of error(E) but, hasn't been given the LOC to use in the problem. My sample size is greater than 30. How do I get the LOC to use in calculating E? should I just assuem a 95% or 99% LOC?Grateful for your support.

    Why do we need the margin of error when according to the central limit theorem with number of samples size equal to 30 or greater and the standard deviation of the population known, the sample means mean is equal to the mean of the population mean?

    A study on the life span of micro drills was conducted in a research paper titled as “Study on the life distribution of Microdrills”.In the research 50 microdrills were taken for experimentation and based on that the average life of micrdrills was 12.68 hours and standard deviation was 6.83 hours.It is known that the endurance limit is within 95% CI.Using figure draw the 95% CI. According to that if the life span of microdrill lies with in CI a customer will buy 1000 microdrills at 1 $ and if the life span lies out of CI,Customer will buy 1500 for 0.3$.Based on that how much a customer will pay?
