The sample distribution for the random variable which follows a binomial distribution, the mean of the sample distribution is the product of sample size and the probability of success. 9. The standard deviation of the sampling distribution is called a standard error, since it measures how much a sample statistic (in this case, a sample proportion \(\hat{p}\)) varies from sample to sample. It should be clear that this distribution is skewed right as the smallest possible value is a household of 1 person but the largest households can be … 100% Upvoted.
