1. sampling distributions

   • sample mean x
     • central limit theorem
       • sampling distribution of a sample mean
         • population n(u, sigma)
         • sample n(u,sigma / square root n)
     • sigma x= sigma/square root of n

2. sampling distributions and proportions

   • binomial distribution
     • binomial setting
       • sampling distribution for counts of succeses
         • binomial mean and standard deviation
           • sample proportion
             • binomial probabilities
             • p roof=x/n
               • p roof = count of succeses / size of sample
           • sigma x= sqaure root n p(1-p)
             • sigma p roof= square root p(1-p)/n
       • fixed n
       • n are all independent
       • 2 categories: failure, succes
       • p is same for all n
     • count x for succeses
