Let the Practice time hour is represented by x and Mistake made by y
So,
from the giventable :
The coordinates are : (4,6), (7,4), (3,7), (2,3), (10,2), (12,1), (9,2), (6,8)
arrenge them in sequence : (2,3), (3,7), (4,6), (6,8), (7,4), (9,2), (10,2)
as time increases the mistakes first increases then decreasing
thus it is a negative corelation
Plot this coordinates on the graph we get :
The plotted graph is similar to the graph C
Answer : C
