Question

Three randomly selected households are surveyed. The numbers of people in the households are 1, 2, and 12. Assume that samples of size nequals2 are randomly selected with replacement from the population of 1, 2, and 12. Construct a probability distribution table that describes the sampling distribution of the proportion of odd numbers when samples of sizes nequals2 are randomly selected. Does the mean of the sample proportions equal the proportion of odd 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. 1,1 1,2 1,12 2,1 2,2 2,12 12,1 12,2 12,12

Construct the probability distribution table. Sample Proportion Probability 0 one ninth 0.5 four ninths 1 four ninths (Type an integer or fraction.)

Choose the correct answer below.

A. The proportion of odd numbers in the population is not equal to the mean of the sample proportions.

B. The proportion of odd numbers in the population is equal to the mean of the sample proportions.

C. The proportion of even numbers in the population is equal to the mean of the sample proportions of odd numbers. D. The proportion of odd numbers in the population is equal to the mean of the sample proportions of even numbers.

Choose the correct answer below.

A. The sample proportions target the proportion of odd numbers in the population, so sample proportions make good estimators of the population proportion.

B. The sample proportions do not target the proportion of odd numbers in the population, so sample proportions make good estimators of the population proportion.

C. The sample proportions target the proportion of odd numbers in the population, so sample proportions do not make good estimators of the population proportion.

D. The sample proportions do not target the proportion of odd numbers in the population, so sample proportions do not make good estimators of the population

1) Three randomly selected households are surveyed. The numbers
of people in the households are 2, 7, and 12. Assume that samples
of size nequals2 are randomly selected with replacement from the
population of 2, 7, and 12. Construct a probability distribution
table that describes the sampling distribution of the proportion of
even numbers when samples of sizes nequals2 are randomly selected.
Does the mean of the sample proportions equal the proportion of
even numbers in the population? Do the...
