Construct a probability distribution table that describes the sampling distribution of the proportion of
numbers when samples of sizes
are randomly selected. Does the mean of the sample proportions equal the proportion of
numbers in the population? Do the sample proportions target the value of the population proportion? Does the sample proportion make a good estimator of the population proportion? Listed below are the nine possible samples.
A.
numbers in the population is equal to the mean of the sample proportions of
numbers.
B.
numbers in the population is equal to the mean of the sample proportions.
C.
numbers in the population is not equal to the mean of the sample proportions.
D.
numbers in the population is equal to the mean of the sample proportions of
numbers.
A.
