Answer:

Correlation coefficient = 0.945 ( approx) and weight of a student increases as the height of the student increases.

Step-by-step equation:

Here, value of x are 58, 59, 60, 62, 63, 64, 66, 68, 70

Value of y are, 122, 128, 126, 133, 145, 136, 144, 150, 151.

∑x = 570, ∑y= 1236, ∑ = 36234, ∑ = 170694

∑xy=78617

Thus the correlation coefficient,

Where n is the number of the term.

here n = 9

thus, correlation coefficient

r =

Thus, r= 0.94452987512

Which is closed to 0.95 and greater than 1

Therefore, weight of a student increases as the height of the student increases.
