The correct option is (b) statistic.
Explanation of Solution
Given info:
The data shows that the percentage of people interviewed were employed is 4.9% and the sample number of households is 60,000.
Reason for correct answer:
Here, the percentage 4.9% is obtained by using the sample of 60,000 households and explains the characteristic of the sample.
Thus, the boldface number is a statistic.
The correct option is (b) statistic.
Reason for incorrect answers:
Since, the percentage 4.9% is obtained by using the sample the options (a) sampling distribution and (c) parameter are incorrect.
Conclusion:
Thus, the boldface number is statistic.
Introduction:
Sampling distribution:
It is the distribution of observations obtained by using the statistic of all the possible samples taken from the population. Here, the size of the all possible samples is same.
Parameter:
A parameter is a value that explains the characteristic of the population. In general, the parameter is estimated by using the sample, because it is difficult to examine the total population.
Statistic:
A statistic is a value that explains the characteristic of the sample. It can be obtained by using the sample of observations.
