If a sample of 14 students were taken from a population of 168 students, could refer to the variance of how many of the students' heights?

a. neither 14 nor 168

b. 14

c. both 14 and 168

d. 168

⇒The Variance tells us spread between each variate in data set from mean.

 Now, Coming to the Question

⇒Sample of 14  students were taken from a population of 168 students.

Variance =Expected value of square of each variate taken from mean, which can be represented as

Size of Sample taken in terms of Percentage

⇒Sample Size is Approximately only 8.4% of total Population,which is very small, that can't represent the whole Population Variance.

Option B:→ 14 , is most appropriate, which Represents the Variance of 14 student height.
