    you're supposed to divide it by n

    shouldn't the last calculation of sigma-phat being sigmaX divided by the sqrt of n?

    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

    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??

      The whole subject is a bit confusing and explaining it might be tricky.

    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

    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

    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.

    why can't you just solve the problem without explaining it and then doing an explanation
