Assume that samples of size

n=2

are randomly selected with replacement from the population of

and

Construct a probability distribution table that describes the sampling distribution of the proportion of

even

numbers when samples of sizes

Construct the probability distribution table

Choose the correct answer below.

The proportion of

even

numbers in the population is equal to the mean of the sample proportions of

odd

numbers.

The proportion of

even

numbers in the population is equal to the mean of the sample proportions.

The proportion of

even

numbers in the population is not equal to the mean of the sample proportions.

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.

The sample proportions target the proportion of

even

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

The sample proportions do not target the proportion of

even

numbers in the population, so sample proportions make good estimators of the population proportion.

The sample proportions do not target the proportion of

even

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

The sample proportions target the proportion of

even

numbers in the population, so sample proportions make good estimators of the population proportion
