Why is no one capable of explaining this topic in a simpler way and then adding all this complex bull shit’s meaning at the end. Just the concept, seriously??
Have u found someone that explains this in a normal way bc. I’m struggling sm with stats
shouldn't the last calculation of sigma-phat being sigmaX divided by the sqrt of n?
you're supposed to divide it by n
very hard to follow... continuous pattern
Mu (x) = n1*p - where n1 is the number of objects in the trial (10 in this case)
if no. of trials in X = n2
Mu(p^) should be = n2* (n1 * p) / n2
Thank you so much!
Only me feelling the explanation is confusing? I prefer the way Patrick teaches.
The whole subject is a bit confusing and explaining it might be tricky.
awesome video! thank you!
I'm concerned how I'm seeing orange gumballs.
Can I ask?
Does the sampling distribution of proportions normally distributed?
If np(1-p) greater than or equal 10 than sample distribution of propotion normally distributed
Thank you.
the last part of finding the mean and standard deviation for the sampling distribution of sampling proportion isn't explained well. That's why it is a dislike from me
This video is an L for Khan academy

Sorry what about this ( a random sample of 10,000 is taken from a population that is known to be 10% defective. Find the probability that less than 1,000 are found defective.
THIS TOLD ME NOTHING
Thanks
.
hi
Khan maths is too hard shoot a video to make it easier XD
i didn't like it
why can't you just solve the problem without explaining it and then doing an explanation
