During the medical check -up of 35 students of a class , their weights were recorded as follows :
`{:("Weight (in kg)","Number of students"),("Less than "38,0),("Less than "40,3),("Less than "42,5),("Less than "44,9),("Less than "46,14),("Less than "48,28),("Less than "50,32),("Less than "52,35):}`
Draw a less than type ogiven for the given data . Hence obtain the median weight from the graph and verify the result by using the formula .
