Answer to Problem 15.17CYS

The correct option is (b) statistic.

Explanation of Solution

Reason for correct answer:

Since the proportion of the people interviewed is based on the sample of 60,000 households, thus the boldface number is statistic because any statistical measure that is calculated on the basis of a sample observation is known as statistic.

Thus, option (b) statistic is correct.

Reason for incorrect answers:

Option (a) says that the boldface number is sampling distribution which is incorrect because sampling distribution is the distribution of a statistic of a given sample.

Option (c) says that the boldface number is a parameter which is incorrect because statistical measure is not a parameter since the situation is based on the sample.

Thus, options (a) and (c) are incorrect.

Conclusion:

Thus, the boldface number is statistic.
