Answer with explanation:

Sample of Students Chosen =950----N

Total Number of students = 77

Probability of choosing a student from 77 students, that is Probability of Success

$=\frac{77}{950}------P$

Probability of Failure ,that is choosing a student from , 950-77=873, students

$=\frac{873}{950}-----Q$

$\text{Variance}(\sigma)^2=\sqrt{NPQ}\\\\=\sqrt{950 \times \frac{77}{950}\times \frac{873}{950}}\\\\=\sqrt{873 \times \frac{77}{950}}\\\\=70.7589$

Approximately ,70 or 71 Students refer to the variance of of the students height.
