Exams, CH 101 General 4) Student (13) WCKED DEFY GR- X/ d, Boston University : NA w.php?id 4143649 4Jump to. ments Normal Density Curves Hint Select the correct definition of a sampling distribution of a sample proportion. O a probability distribution of the sample proportions of a certain characteristic of interest for all possible random samples of size n taken from the population O a probability distribution of the count of a certain characteristic of interest for all possible random samples of size n taken from a population O a probability distribution of the sample means for all possible random samples of size n taken from a population O a probability distribution of the population proportion of a certain characteristic of interest 0 a probability distribution of a sample proportion of a certain characteristic of interest for a random sample of size n taken from a population ScrollExplanation / Answer
answer is (a) : the sampling distribution of a probability distribution is as if we draw all possible samples of size n from a given population and compute a statistic (e.g., a mean, proportion, standard deviation) for each sample.
A sampling distribution is a probability distribution of a statistic obtained through a large number of samples drawn from a specific population. The sampling distribution of a given population is the distribution of frequencies of a range of different outcomes that could possibly occur for a statistic of a population.
Also, The Sampling Distribution of the Sample Proportion. If repeated random samples of a given size n are taken from a population of values for a categorical variable, where the proportion in the category of interest is p, then the mean of all sample proportions (p-hat) is the population proportion (p)
