i was learning this at my add maths tuition and then when i opened youtube, khan uploaded this vid seconds later! gr8
Can somebody answer where the 0.25 value came in the Y value in the density curve please ???
0.25 is the probability density value, in this case they all have 0.25 values. hope that helps a year later :)
What numbers are calculated to get the 34%, and the 50%. This is where I get confused, when there is not a clear path on what numbers will be computed to get the answers. Also, why is everything under the curve added up to 1?
Please
WhatsApp is the software you are using to do this video ?
What
how is that 34% ??
Diana Ica he's said P between sd below the mean and sd above the mean roughly 68.2% in normally distributed. I'm not sure wait for correct answer.
James
