  • 0:00 - 0:06
    Let's now apply what we just learned in the context of computing an actual confidence interval.
  • 0:06 - 0:09
    Suppose I care about 90% confidence and from my coin flips,
  • 0:09 - 0:17
    I get a data sequence of 5 elements 11000 and let's for now assume you're going to use the T table.
  • 0:17 - 0:20
    This might not be the world's most accurate method but for now we do this.
  • 0:20 - 0:24
    Now we've computed the variance many times. I'm just going to give it to you.
  • 0:24 - 0:33
    This 0.24 and if I knew this five takes the square root of the variance over n is about 0.219.
  • 0:33 - 0:38
    You compute this so many times, these are just the numbers, but I want you to give me
  • 0:38 -
    is the confidence intervals, which is the mean plus or minus the term on the right.
