| 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) | Sample size |
| (C) | The number of objects in a sample is called | (III) | Null hypothesis |
| (D) | A tentative assumption about population | (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)
These are the basic terms of inferential statistics.
(A) The measurable characteristic of a population is called
This matches (IV) Parameter.
A parameter describes the population, such as the population mean μ.
(B) The measurable characteristic of a sample is called
This matches (I) Statistic.
A statistic is computed from the sample, such as the sample mean \( \bar{x} \).
(C) The number of objects in a sample is called
This matches (II) Sample size.
The number of observations in a sample is its size n.
(D) A tentative assumption about population
This matches (III) Null hypothesis.
The null hypothesis H0 is the assumption about a population parameter that is tentatively accepted and then tested with sample data.
So the matching is (A)-(IV), (B)-(I), (C)-(II), (D)-(III).
