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.
