| LIST-I | LIST-II | ||
| A. | The measurable characteristic of a population is called | I. | Statistic |
| B. | The measurable characteristic of a sample is called | II. | Confidence level |
| C. | The percentage of all possible samples that can be expected to include the true population parameter is called | III. | Confidence interval |
| D. | A range that could be expected to contain the population parameter of interest is | IV. | Parameter |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → A - IV, B - I, C - II, D - III
(A) The measurable characteristic of a population is called
This matches (IV) Parameter.
A parameter describes the population, for example the population mean μ.
(B) The measurable characteristic of a sample is called
This matches (I) Statistic.
A statistic is computed from the sample, for example the sample mean \( \bar{x} \).
(C) The percentage of all possible samples that can be expected to include the true population parameter is called
This matches (II) Confidence level.
A 95% confidence level means that 95% of all possible samples give an interval containing the parameter.
(D) A range that could be expected to contain the population parameter of interest is
This matches (III) Confidence interval.
The confidence interval is the range of values itself.
So the matching is A - IV, B - I, C - II, D - III.
Tip: Population goes with Parameter, Sample goes with Statistic (P with P, S with S); the confidence level is a percentage, the interval is a range.
