| LIST I | LIST II | ||
| A. | A special characteristic of a population is known as a: | I. | statistic |
| B. | A special characteristic of a sample is known as a: | II. | Confidence interval |
| C. | The uncertainty of a sampling process is expressed by: | III. | Estimation |
| D. | The process by which one makes the inferences about a population based on the information obtained from a sample is known as: | IV. | Parameter |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → A-IV, B-I, C-II, D-III
A. A special characteristic of a population is known as a:
This matches IV. Parameter. A parameter describes the whole population (for example the population mean \(\mu\)).
B. A special characteristic of a sample is known as a:
This matches I. statistic. A statistic is worked out from the sample (for example the sample mean \(\bar{x}\)).
C. The uncertainty of a sampling process is expressed by:
This matches II. Confidence interval. A confidence interval gives a range for the parameter with a stated confidence level, which expresses how uncertain the sample result is.
D. The process by which one makes the inferences about a population based on the information obtained from a sample is known as:
This matches III. Estimation. Using a sample statistic to judge the value of a population parameter is estimation.
