(A) - (I), (B) - (II), (C) - (III), (D) - (IV)

(A) - (IV), (B) - (III), (C) - (II), (D) - (I)

(A) - (IV), (B) - (III), (C) - (I), (D) - (II)

(A) - (III), (B) - (IV), (C) - (II), (D) - (I)

✅ Correct Option: 3

Population refers to the collection of objects having the same characteristics. This is the entire group under study.

(A) POPULATION → (IV)

Sample is a finite set of statistical individuals drawn from a population for investigation. This represents a smaller portion taken from the population.

(B) SAMPLE → (III)

Parameter refers to measurable characteristics of the population such as mean, variance, standard deviation etc. of population. These are measurements calculated from the entire population.

Statistic refers to measurable characteristics of the sample such as mean, variance, standard deviation etc. of a sample. These are measurements calculated from the sample data.

(D) STATISTIC → (II)

The correct matching is:

(A) - (IV)

(B) - (III)

(D) - (II)

Consider the following hypothesis test:

$H_0: \mu \leq 3432$

$H_a: \mu > 3432$

A sample of 96 provided a sample mean $\bar{x} = 3648$ and sample standard deviation $s=802$ then the degree of freedom of t-distribution is:
