# suppose a simple random sample of size n=200

&= \dfrac{{50}}{{200}}\\ (a) Describe the sampling distribution of ._____(b) What is the probability of obtaining x = 136 or more individuals with the The sampling distribution of the sample mean x-bar is the probability distribution of all possible values of the random variable x-bar computed from a sample of size n from a population with mean Î¼ and standard deviation Ï. Similarly, for the sample mean and sample proportion, the probability distribution follows a normal distribution.
