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


=(77)/(950)------P

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


=(873)/(950)-----Q


\text{Variance}(\sigma)^2=√(NPQ)\\\\=\sqrt{950 * (77)/(950)* (873)/(950)}\\\\=\sqrt{873 * (77)/(950)}\\\\=70.7589

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