allochka39001 [22]

It is true that To "Derive" means to get an equation from a specific information.

<u>Explanation:</u>

If we have an equation, we can easily answer various questions. The equation is derived by the data given, observations, results and assumptions. We also need to consider the law and theories while deriving an equation. While deriving an equation, the dependent and independent variables are arranged accordingly.

<u>Example</u> - To derive the formula of a quadratic equation.

  • To derive something that is not an equation means to come to a conclusion from the results of the data obtained.

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
tensa zangetsu [6.8K]

⇒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

      =\sum_{N=1}^{k} \frac{E(x-\mu)^2}{N}

Size of Sample taken in terms of Percentage

                    =\frac{14}{168} \times 100\\\\=\frac{100}{12}\\\\=8.\bar{3}

⇒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.
