Hi,

Can anyone help me in solving this question using newton interpolation formulae.

From the following table, estimate the number of students who obtained marks between 80 and 85

Marks 40 50 50 60 60 70 70 80 80 90
No. of students 40 78 10 3 19


Please mail me the solution at lalitchugh@yahoo.com
